Title: Corona for C4D A6.3 testing
Post by: Nikola on 2017-03-24, 23:03:53
Hi all,

because there was a lot of problems connected to normal maps we are releasing Corona for C4D A6.3. We fixed problems with normal map strength settings, problems with normal maps when projection other than UVW mapping was used and various other issues connected to normals. We also fixed not working motion blur when command line render is used and crashing of Corona when displacement was used mainly for bigger scenes.

I would like to ask you for testing the A6.3 version, and if it is OK, we will change the download links on Corona download page. Here are the links for testing:

macOS:https://drive.google.com/open?id=0B7xyYS3daSJ7WV9pYS1ObkVCamM
Windows:https://drive.google.com/open?id=0B7g1HtV8lD7gekZnVlJuSXkxcnM

Thanks, under test now.

Edit: normal maps are ok with every kind of projection mapping. I must force exposure a bit to have best results. No more crash with displacement with my outside forest macro scene. Motion blur ok.

Thanks Nikola. That's a late finish for a Friday! Will test as soon as I can but sounds like the fixes are working well. Also appreciate the work done on displacement crashes. If that works it will save a lot of last minute headaches.

Here on Windows 10. C4D R18

Normal mapping works fine now. Great work! Thank you guys!

Definitely an improvement with 6.3 normals! I rendered some screws out. I have attached some before/after. A zoomed out render still looks a little wavy. Not sure if it's a bug or if thats just the nature of it? Also the VFB still says hotfix 2. Not a huge deal, but just thought I'd let you guys know :P

THANK YOU SO MUCH!

Thank you for testing mrittman. Would it be possible to send us your scene so we can make sure that there is no problem with e.g. filtering in zoomed out case? VFB is showing version of Corona core used by CornaC4D plugin but it is quite confusing. We should include the version of plugin in the title too same like in about dialog.

Hi Nikola, alas im still getting problems with that paving file. When using a substance I still get the lines, and when using the bitmap versions in the normal shader it doesnt really show up. I have the mapping set to 0.75 cubic. If I switch it between uv and cubic I different outcomes but neither are right. When I set it to 3000% I get the lines back using the bitmap files. No matter which way I try it, there still seems to be an issue for me. Sorry to be the bearer of bad news. Looks like its fixed some stuff for other people so Im not sure why this is such a problem case.

Also to confirm the preview box is black is that right?

Thanks for looking in to this.

Hi, could you post the c4d file with textures?

Here's a link. I've stripped it down to key textures and omitted the original substance. But it would be interesting to see if anyone else has a problem rendering this from just opening and rendering. Ive set the strength to 3000% otherwise nothing shows up really. Weirdly the preview ball looks OK.

Hi, i've tried your file and the problem is the cubic projection. If you use uvw mapping there are no more lines. I think that this happens because uvw mapping is linked with geometry. With cubic projection there are lines if you use a simple bump fdm noise (put 5000% strentgh to see it).

In the second image you can see the difference between the floor with UVW p.map and the cube CUBIC p.map.

I can confirm this problem is connected to cubic mapping. I am trying to find what exactly causes these artefacts now. Would it be possible to create some similar normal map and texture but with less detail and export it from substance shader in the same way like paving texture and map? I am trying to find out wich part of normal map causes the artefacts whether is there some offset between texture and normal map or flipped axis and so on.

I don't need it anymore. I just found that this problem occurs only when "Tile" is on when "Cubic" projection is used. So I am now looking into code what can be wrong.

Ah brill. Hopefully tracking it down to that is half the work. I wonder if this has any connection to bump mapping? I find it a bit hit and miss and much less pronounced than Vray

Ive attached a couple of examples. A diffuse grey with some reflection on both so only the bump is providing the texture. I have had to crank the corona one up to 800%. Whilst I much prefer the light and look of the corona one it cant be denied that there is more detail in the bump in the vray version. The first example uses a karate tile shader with random planks and the second is a regular tile.

Hi, to me it looks like the Vray version has a completely different lighting setup, which makes the bump features more pronounced, whereas in the Corona scene, you have pretty much flat lighting, which flattens the bump too.

dude,trust me,corona bump has big problem.do it yourself,you'll know it. corona version A3's bump is right,after version A3,all version's bump has problem,big problem with noise and texture.

PLZ fix it...

PLZ.

Hi , thank you for the answer.For some more clear information about the crash I'm getting; on Cinema 4D versions r16 and r17 are the only versions I tried Corona.I also tried Corona Renderer on a Cinema 4D r17 on Windows , there was no error or crash happened with Windows.The main issue is with MacOs Sierra.There is no problem with the Corona Sun , Corona Sky , Light or Camera.They all work charm.But after you change renderer from Standart to Corona and hit the picture viewer Corona Crashes.Materials aren't working either.When you create "New Corona Material" it gives the same crash report and Cinema app shuts down.None of the versions of Corona I could found worked with MacOs Sierra.All gave the same crash report on the same act.

I think this is exactly the point. They do look markedly different. Even though it was just a quick test, they are both lit by a sun from roughly the same direction and have a grey diffuse texture. They both have a semi rough gloss reflection but I think the vray one is a bit more glossy by default / ior fall off. But they are basically the same scene using the same bump textures. I think corona pics up a higher frequency noise which just makes the surface universally rough where as vray looks like grooves in the surface and gives more of the expected texture detail and 3D feel. I think this is partly why the corona one looks more matt and the vray one more shiny.

I just upgraded to Mac OS Sierra 10.12.4 and Corona a6.3 and I am able to hit render in the Picture Viewer no problem. The materials all seem to work as well. I even switched the renderer to Standard and back to Corona and still no crash. So it seems not every Mac is crashing like this.

Hi,

First of all thanks for the amazing work ! I worked on Max \ Corona and loved it so much that when i had to switch to C4D \ "He-Who-Must-Not-Be-Named" i was really sad, but this alpha seems already advanced enough for me to convince my boss to let me use it in the production and i can't be thankfull enough !

So i read the road maps \ forums and obviously a lot of things are coming \ planned, but i haven't found \ read anything about a simple tool that my coffee-head could have used this morning.... "Render elements only". Like in "damn i forgot the Mask Render Elements before leaving yesterday" tool. Anything on this ?

Thanks in advance and keep up the good work, can't wait for the beta !

Hi all,

we finally fixed the problem with normal maps when cubic mapping was used and strength was set to high value. I would like to ask you for testing the A6.3 version, and if it is OK, we will change the download links on Corona download page. Here are the links for testing:

macOS:   https://drive.google.com/open?id=0B7xyYS3daSJ7WV9pYS1ObkVCamM
Windows:   https://drive.google.com/open?id=0B7g1HtV8lD7gekZnVlJuSXkxcnM

This should be the last Alpha 6 version because we would like to focus on the development of Beta 1 version.

Hi Zbieraj,

Would it be possible to send us the scene (you can simplify it in any way if it will still cause the problem)? I am afraid it is hard to reproduce such bug without the scene.

Could you send us the scene please? :-) Or if it is something that you'd rather not send, you can try to reduce it so that the bug is still in there, but the scene does not contain sensitive data anymore.

About the scene going black - whenever (no matter the scene and the file) I am using more "heavy" file and rendering in high resolution, the image can go black after some pass if the "Bloom and glare" are turned on.
