Thank you! :) I will check it out tonight with some of my scenes in c4d r15.

[koldi]

Thanks a lot for this one. Would you say using standard 1.9 vray mats is safe now, or rather stick to navite c4d when using your plugin? I got projects to finish with vray but I cant wait to continue started ones with corona. Good work anyway.

Since VrayMaterials aren't supported yet, it's quite safe. ;)
Currently, only C4D standard materials are supported. I'm currently implementing the vray conversion template, so its release will be in the next few days. After that, additional C4D+Vray materials templates will be implemented. After C4D + Vray conversion is working 100%, Octane will follow. (Since C4D & Vray are the most common used ones)

Lovely mp5gosu i will wait for the vray conversion since i dont use AR engine for so long, but for who was using AR they can test already your nice tool! Wainting for the vray conversion to be avaiable, thank for your efforts!

Update 1.1 arrived. :)

[Marvey]

nice mp5gosu!

[pBarrelas]

Many thanks for taking the time to make this material converter! Greta job!

[mp5gosu]

Update arrived, see 1st post. :)

[Marvey]

First and fast impression, just tried to convert a scene just to test, seems very nice, just noticed some names in the conversion got mixed (names with the material settings), for exemple in vray i got 2 materials, one with the name tree1 and other with tree2 after conversion the material with the name tree1 was the tree2 and the tree2 was the tree1, some others names got correctly converter others not.. other thing i noticed was the translucid materials (2sided vray materials), seems the conversion only activate the translucid channel and put there the color and texture, no difuse,  reflect, bump etc was activated, it is possible to get a better conversion of the translucid materials? other thing is the bump scale conversion, till today i dont understand yet very well the scale of the corona bump, but i noticed the corona scale  after conversion is exactly the same as vray, i have the feeling corona use a lower scale, since my tests till today with bump show me that i need to reduce the scale of bump to get a real material bump. Another thing is the opacity channel, i read the notes and yes i know is not doing the conversion yet, so will love to see it able to convert the opacity in the next builds. After all good work! it is already a big help, anyway i hope you continue improve the converter and if possible fix the things i said, no idea if is possible but i hope so :)
best regards

Hi, thanks for the input.
Names usually don't get confused, but it might seem so as Blend and 2Sided Materials only use 1st slot for conversion. Therefore, for example the 2Sided Material will inherit parameters from the material of the first link - it will even inherit its name which is practically not correct, I'm gonna fix this. :) I know, it's a solution with a few drawbacks, but it will be changed once Corona offers Mix Materials.

Translucent materials: Translucency inherits the Diffuse texture from the first material's diffuse channel as this gives the very best results. (Btw, it's the same way as it is done in the converter for Max)
However, all material parameters are only convertible to a certain degree and especially translucency is such a case where it comes to massive drawbacks.

Bump scale ist broken. As I was thinking about to implement a scale factor, this is nearly impossible. This would count for ANY scale parameter in any shader. But I'm pretty sure, this is going to be fixed soon.

Thanks for input again. :)

edit: Found a bug that was causing Material Name Mismatch. Will be fixed in next version. :)

[Marvey]

Thank you for your work mp5gos!

Version 1.2 not work in r16

[mp5gosu]

Okay, I'll have a look into it tomorrow.

[Dex]

Open Corona Material Converter 1.2 . Uncheck  "convert Cinema 4d Materials" & "Convert Vray Materials". Press the CONVERT button. Then turn on Vray if you need vray converted or Turn on Cinema4d materials. Try a Convert again.

The conversion worked again for me!

Great plugin mp5gosu. You are a clever dude, you will save users many hours. Appreciate all your hard work.

[Marvey]

Version 1.2 not work in r16

Strange here R16 v1.2 with no probs to run the script.

[mp5gosu]

Version 1.2 not work in r16

Bug found, fix will follow with the next update. Thanks for the report anyways. :)

edit: Temporary solution applied

1.21
Fixed: R16 Reflectance conversion error resolved

[Marvey]

thank you

[alekba]

As far as I know the ideal material converter does not exist, there are always remain some details to fine tune. Your plugin does a great job, it would be good to be included in a future version of Corona. Thanks for this.

[xcut0r]

where's the "thumbs up" button when needed? :D

great job there @mp5gosu !! thanks for this men, its very very usefull !! :)


cheers

xcut0r

[mp5gosu]

A quick headsup:
Since migrating to C++ Base, I'm making good progress.
However, the next update will probably take a while because I decided to overhaul the Converter. That means, that in the future you will not only be able to convert materials, but also whole scenes. Things planned on upcoming releases: A SceneConverter, LightLister and some other handy tools.
The current version of the Material Converter will receive an update though - to allow conversion of R16 reflectance layers.

So stay tuned. :)

[Marvey]

very nice, waiting for it! thanks

Is it possible, that you didn't install 1.2 properly?
Please double-check at the Corona About-Dialog.
Btw, you should update your C4D-installation to the most recent version.

[mp5gosu]

I applied a fix, re-download if you experience any issues.

[Seik]

Can we have a "retro" function to convert Corona Materials to Standard Cinema 4D Materials?

[mp5gosu]

Can we have a "retro" function to convert Corona Materials to Standard Cinema 4D Materials?

Yes. But this will take quite a while. I'm currently rewriting the plugins and extending it to a Scene Converter. After that's done, I'll add the possibility to convert to Cinema 4D Scenes.

[Seik]

Great. Thanks.
Do de best to develop for OSX too guys ;)

[Dex]

Thanks for releasing v1.3.

Just a small thing. Click on the '?', Help and about shows v1.2.

[pBarrelas]

mp5gosu, many thanks for releasing this plugin. It's a real time saver!

[mp5gosu]

You're welcome.
Version 2.0 is already being worked on. Scene Converter works good so far. There are still some things to do until next release. Hopefully, in the next weeks I'l be able to release the new version.

[Karol Nord]

Any chance to see this work in R14? It would be incredibly helpful to make the switch to corona.

[mp5gosu]

R14 support is planned, but the lowest point on my priority list. ;)

[pBarrelas]

I noticed that when converting Vray materials that are using the Vray Bitmap Loader, the script translates it to the Corona material. Any chance of the script being able to get rid of it?

This isn't fixed in 1.3 though. :)
I'm still porting everything to C++. The Python version can be seen as obsolete. The new tools will take me some more time as Corona advances quite fast. :)

[pBarrelas]

I downloaded the latest version from your website but in the "about" section it still says Version 1.2. Is this correct?
Yes, it's good that Corona advances this fast but I guess that when you're porting plugins from Python to C++, this my be a pain in the neck :)

Current is 1.3 - 1.2 is just a typo. :)
My company "allowed" me  to work on the converter fullt-time now, so I'm making progress more quickly. A first testbuild went out to some testers yesterday - yet there's still a lot to do.
With the next public release, I can actually make sure that all features are supported. IES, SSS, Multipass ,etc.
And yes, porting to unmanged code is definitely a pain in the neck. :)

One thing that the conversion isn't taking care of, is that the Normal Channel from a C4D material should go to the Bump Channel from a Corona material. Probably this is already planned for the C++ version.

[adildil]

need vray converter pleaaaaaaase

[digitalmarley]

Hi your plugin is very valuable so thank you for creating this. I've noticed that with Corona Alpha 3 for C4d, it includes a 'scene converter' that also does material conversion. Is this the same as your plugin because the material converter 1.3 does not work in the new alpha build at all. If they are the same plugin, thats great that its included in the new build.

Problem i am having with 'scene converter' material conversion hangs forever on most conversions. I am using C4d V16 build 16.050 so i'm up to date. Its typically in files with lots of materials. One or two and it works immediately...any more than 10, and it hangs forever. I've left it running over-night so i know i'm not being impatient.

What other factors might cause the scene converter's material conversion to hang? Long material names or long file names for the textures?

Any help you can provide would be appreciated.

DM

[mp5gosu]

Hi,

there are some problems with C4D shaders that are not supported by Corona. I plan to add a filter for unsupported shaders, but with the current build it's easy to crash Corona with certain shader-setups. This has to be handled by Corona as you are able to crash Corona even if you do it manually.
However, I'm going to add more failure checks to support stability.

Even with 2000 materials, it takes less than a half-second on my machine.

The MaterialConverter is just a script and deprecated, therefore it should not be used anymore. (Use it as long as you want to convert Vray materials though as in the current build of the scene converter, there's no vray support yet - follows with the next update)

[digitalmarley]

Thanks for the quick reply! Are there any particular types of shaders you know of that  i can filter manually in the meantime? I have to hurry on this project! Strangely they are all simple c4d materials, created by C4d when importing a DAE model. Nothing fancy like dirt shaders, luminance or even reflections. In fact they are all pretty much just Diffuse channels with the occasional JPG texture in the image slot.

Any thoughts?

DM

[mp5gosu]

Can you provide a stripped file with only materials in the scene via PN? No textures, no objects.
This way I can at least check if it is caused by Corona or by the converter.

[digitalmarley]

Absolutely. Here's the simplest of the 5 files i have to convert, just the materials and the linked textures. As you can see its crashing with just the 16 or so textures and all except thje glass is just a diffuse channel.

My other files have thousands!

Thank you so much for your attention and help,

DM

[mp5gosu]

Thanks. Bug found. I made a mistake. Will release a fix tomorrow. :)

[digitalmarley]

You are awesome! Thank you!

[mp5gosu]

You are awesome! Thank you!

Quicker than expected. This should fix your problem: http://www.roberthitzer.de/projects/coronatools/coronatools_r16_beta_1.rar

[digitalmarley]

it worked perfectly!!!! you are a great developer! I will now test more complex files, see what happens and let you know!

DM

[digitalmarley]

OK ive tested a file with 228 textures, and a file with 2091 textures, and they both converted in seconds. Whatever you did was a lifesaver!

Thanks again and promote that plugin beta update immediately!

DM

[_David_]

Thanks for your work on this. It's going to be very useful for converting Vray materials/scenes. I'm a bit behind with Cinema version r14 though so will have to be patient

[mp5gosu]

Yes.
The next version is almost finished. So R14 is getting a bit closer. :)

[mlon]

r14 yea! :)

[Karol Nord]

so how's this r14 support coming along? :)

[Dex]

+1 Great job with the scene converter, really appreciate your hard work.  I would love the hear how it is coming along, and when the latest version will be released with Vray support.

[mp5gosu]

Hi. Thanks for those kind words. Due to the current lack of sparetime and the recent summer, things take a bit longer than expected. The next version will definitely come with Vray-Support.
I'm currently adding support for R17 & GI portals and additional stuff. So no e.t.a. yet, sorry.

I'll update this thread accordingly whenever I release an update. :)

[Marvey]

thats would be perfect! thanks!

[Dex]

Thanks for your reply. I'm sure the C4d corona forum would help if asked. Can you create donationware software?
Don't want to be a pain in the ****, but can I ask..... you think it would be available before the new year? :D

[mp5gosu]

Thanks for your reply. I'm sure the C4d corona forum would help if asked. Can you create donationware software?
Don't want to be a pain in the ****, but can I ask..... you think it would be available before the new year? :D

The converter won't be donationware. Chances are good that there will be an update before 2016 as the core features are implemented yet.

[Dex]

I'm probably doing something wrong here!
Using the latest scene converter on a standard c4d material with an alpha applied. It inverts the alpha channel. So I end up with the areas I want to keep invisible. Where would I find the alpha channel properties in the corona material so I can invert it?  I can't quite work out how to use the alpha within the layerset! Thanks

[mp5gosu]

I'll take a look into it.


A quick heads up:
Vray support is now almost almost complete. The last thing I'm going to add is environment conversion.
After that's done (and probably the documentation), I'll release an update - hopefully until end of the week. :)


So stay tuned. :)

[Dex]

Thanks so much. I really appreciate your hard work.
If you could have a look at the alpha channel issue, that would be great. It's probably something stupid I'm doing!!
Not an issue or bug, but I would prefer to see the converted textures have less specular by default (that's just my preference). :)

Keep up the great work.

[mp5gosu]

1.0 released.

Please see 1st post. :)

[Dex]

Thanks very much for the update. I will test it out properly over the next few weeks.
I'm still having issues with the alpha channel. The alpha is inverted! (please see the previous message).  Is anyone else having issues?

[mp5gosu]

Alpha works fine here. Can you provide an example file?

[Rhodesy]

Thanks for this tool mp5gosu, a great way to quickly switch over maps and lights. Good work.

[Marvey]

indeed! very nice thanks!

[mp5gosu]

There's indeed an issue with alpha on Vray materials. Unfortunately, Corona is missing an "Invert" checkbox. I'm afraid you'll have to wait for it to be implemented. :(

Btw, I forgot to implement bumpmap-conversion for Vray materials. :D
Update will follow tonight, including support for rounded edges-shader.

[Dex]

Do you know if the corona development team have implemented the invert button in the new Corona version A4.1?
Any inside knowledge when it will be 4.1 will be released? :D

[mp5gosu]

I don't know anything, sorry. :D

[Visual Pie Workroom]

Hi! any further development plans coronatools?

[mp5gosu]

Not this year, sorry.

[Marvey]

ouch thats bad news :(

[anton taf]

Hello and thanks for the tools.
I have one question. Is it possible somehow to convert backwards all corona materials to c4d materials?
The reason I want to do this is mainly because I would like to export my scene or some objects in FBX file, but with corona materials it loses all the texture maps. Or if you know a way to export my scene with all texture information in my geomeries. Thanks

[mp5gosu]

Hi,

it's not that easy, even the way it is right now. When converting,  the tool has to consider not only textures, but shaders of certain types that must be analyzed and brought into the correct context.
So no, the advantage of reverse conversion is too little, it wouldn't defy the effort if implementing such functionality...

[shane_w]

Now that the OS X version is in Alpha would it be possible for a Mac compile of your plugin?

Thanks,

-Shane

[leo3d]

Hello

Would you plane to support substance shader ? Cause we loose some informations (Reflection & bump)

[nightwalker]

Thanks for a great job! Any chance to have this tool for Mac os x?

[mascal]

.... please,  OS X version :-) !!!!

[Marvey]

any news about some update for this amazing tool? thanks!

[mp5gosu]

Currently not. I planned to wait fot final release. Expect in around somewhere in summer.
This includes an OSX version of course. :)

[leo3d]

substance shader support will be very nice quickly ;)

By the way, I'm currently investigating. ;)
Edit: There's actually a corona scene converter on the devs roadmap. So probably no need to update this one. :(

tho, i agree, with 3rd party exporter some work would be taken off the dev. team & users/testers could do more helping, advising, sharing experience

Yes, I see. Will evaluate this usage of this converter and consider if a complete rewrite makes sense.

Hi Robert,

I only would to ask if you're planning to develope Corona Tools compatible with macOS.

Thanks!

Yes.

I'm using the R17... I just copied the folder in the plugins folder but it doesn't work :(

[iacdxb]

Looking for Mac... at least some basic materials to convert....!!!

[chvlad]

Yes, for MAC please

Hey Robert,

I used your great plugin to convert a scene. I noticed the displacement didn't come through quite right however. I know it's been discontinued, but is there any chance at all you'd be making any future updates past version 1.1?

Thanks man!

Hey Matt,

I'm afraid, there's currently no plan to update it, for the following reasons:
Corona is still in development and changes are quite hevy to keep track of.
Corona is awaiting a node-based material system. So there is another point I have to consider in order to make it work with the converter.
And finally: Corona will have its own native scene converter in the future.

Cheers

Okay that's totally understandable :) I can't even imagine the work involved in making a plugin like this. Thanks again!

I know this is discontinued but I use it almost daily. Is there some limitation for object or polycount? Converter freezes but after deleting some objects I try again and it works.

This is most likely happening because of assigned materials, etc. What C4d version do you use?
If you are able to share the scene in question, that'd be very welcome.

I use r19. I work with archviz projects. There may be large amount of polygons in scene but material count is not very high.
I work under nda and unfortunately cannot share these projects.

Good news everyone. Recovered the source files and will start updating the tool again soon. :)

[BigAl3D]

Good to hear. The devs don't seem to think this is a useful tool. Will your tool hand materials with Reflectance correctly?

It's a bit complicated to calculate reflectance correctly because there's always differences in the rendering equations. So at least, there's an approximation.
There's definitely going some research into that, I assume a sample-based lookup table might give nice results. :)

Will see how it works out.

Great to hear. Any converter is better than none and a good converter is an invaluable help.
I converted plant materials the other day, from the content browser. They were in this silly MAXON PBR material format where everything is crammed into reflectance (diffuse, bump, reflections ...) and the Corona material converter failed to take them apart and re-assemble them into a Corona material.
Would be great to have a solution for such cases, too.

[BigAl3D]

@Cinemike Yeah, I stopped trying to use the Convert Scene button. It's easier to create a Corona material and copy the assets from the C4D version. The converter is completely useless. Why even put the damn button in there at all? There are many other "features" that still don't work. How many years with this go on?

[haffy]

This plugin sounds amazing, but I can't get it to work in R23.

Is  this correct, drag the content to ../plugins/ folder and start C4D?
Where should I se it?

There's no plugin for R20+ available yet.

[leonkerpel]

that's nice to hear! if there could also be a function to convert (back) to standard c4d material that would be even more awesome. I know U render has that option.

[BigAl3D]

Corona was supposed to also convert Vray materials as well. That was before Chaos bought them. They are similar in nature, but nothing for that option either.

[kraphik3d]

@BigAI3D

In order to convert vrayforc4d scene and materials into corona renderer you need to have vrayforc4d installed.
Plugin is working ok but you need to adjust shaders manually as they are not the same render engine.
You can also use Corona renderer native converter. Not sure if corona renderer converter or plugin is better though because both do the
same but I think plugin has better options for more experienced users like myself. For example you can only convert selected material
in plugin options and you don´t have to convert all materials at once but only those you need to have for rendering.

I call conversion between render engines "hands on the pocket" conversions because these are
not all very handy and not 100% conversion.

[BigAl3D]

@kraphik3d Good to hear, but I guess it only makes sense if you are switching from Vray to Corona and already have assets to convert. I was hoping to be able to find Vray materials and convert them to Corona. Not the end of the world. Thanks for the info.

[kraphik3d]

@BigAl3D

Typically in customer production there is some use for scene converter when converting some furniture models with
basic c4d materials into corona shaders.

Sometimes it is useful when I have purchased some assets from Evermotion which are in vray format.
First one is converted with built in converter without any manual work and second is converted with scene converter plugin with some manual work.

Last one is original vrayforc4d version.

Of course conversion is not straightforward and you have to remake some materials.

Hi, does anyone know if there are any plugins to convert Vray scenes to corona in cinema R25?

[Beanzvision]

Currently we are working on a better scene converter to bridge this gap. But currently, you might be able to use the following plugins: VRay to C4D then C4D to Corona using our scene converter.
