Hello, is there any way how to get all these nice materials from the Corona website https://corona-renderer.com/resources/materials/ to the Maxon Cinema 4D files? I use only Cinema version of Corona plugin and dont have any access to the 3DS Max.
As a begginer (in Corona), these materials can be very usefull as some starting point. I already found C4D database http://corona-materials.de, but there are only a few naterials...
Any way to re-create 3DS Max corona material to C4D Corona material? Thanks in advance.

I am not familiar with any Max > C4D exporter or anything similar, so the only idea I have is downloading trial version of Max, opening the materials, and simply copy-pasting the values to C4D. Not very convenient, but should work...

Hi there

I am thinking about start working with corona for my archviz projects. I work with C4D and since there is a lot of preset models for 3dsMax + Corona I wanted to ask if it is easy to transfer them to C4D + Corona

for converting models (3d objects) it was very good. converting materials didn't work so well. but hey, it was v2 back then. and conversion only was possible for vrayforc4d & c4d ar. with the latest v4 a lot more renderers are supported now (including corona). but beware, v4 seems  to run only with c4d r20 and earlier.
i'm just wondering if there will be a version, which supprts c4d r21 in future.

I've not had any luck with the latest version unfortunately. it does a mediocre job at best converting vray (max) to vray (max), and all i get is white materials when i convert from corona (max) to corona (c4d). In most cases I end up rebuilding the materials from scratch. I've contacted the creator of the plugin and he keeps saying a new release will be out to fix it.. but it's probably been over a year since then and i haven't seen any updates. Also claims there will be a way to go the other direction as well.. from c4d to max. but that's a different story.

According to the roadmap, in a couple months time, there might be no need to convert materials anymore: https://trello.com/b/EfPE4kPx/corona-road-map-3ds-max

i hope c4d users can take advantage of this feature, too. on trello "corona c4d roadmap" there's no hint for such feature...

It looks like on the trello roadmap, it is in the pool of features to be considered. Here is a link to the feature request. https://forum.corona-renderer.com/index.php?topic=27545.0

Hey Romullus, did the team get anywhere with this, I'm currently using 3dtoall, but its basically a fbx export. It would be interesting to see max files being able to open in c4d or some sort of importer. We waste so much time buying models that then need retexturing.

I have no idea what's the status of that feature, sorry. You'd better ask someone from the team about that.

I created a couple of scripts for this specifically you can use for free if you like. You can alter them to do some more things its in the readme how to do this. Ill expand on this next year but at the moment I made it just for my workflow - basic vray roughness -> fbx then on convert the materials to either vray or corona in c4d.

At the moment I think there is an issue with the metalness (when not using a metal texture and metal using numeric value only), its on my to do list but otherwise should do the trick when using metal bitmaps. If you have 2sided vray materials it will use the front material, also on my to do list is convert the color-correct nodes as if its being used it will ignore these materials for now (keep as vray mat).

Script is now updated with Metal numeric values working, Color Correction & Falloff nodes will be replaced with the diffuse texture. Also works with multi-sub materials (any depth) since its just looking for Vray Classes. You can add your own Vray classes at the bottom (read the --notes). You can reference the Vray2SidedMtl class to see how to add your own its quite simple to do so if you have some basic coding experience.

Convert from 3dsmax Vray -> FBX
https://github.com/jmdvella/3dsmax-scripts

Convert FBX -> C4D (Corona/Vray)
https://github.com/jmdvella/cinema4d-scripts

Feel free to give me some feedback, or you can edit the scripts to suit some specific things in your workflow if you know some basic python/maxscript.

Is there a chance to make a corona scene converter from 3D Max to Cinema 4D?

I tried 3D To All but it doesnt work all the time sometime i have to reboot max oder cinema because it doesnt overwrite the files i exported 10 minutes ago even if i delete them manually it doesnt rewrite them ... :-(
