[C4D] Daily Builds / Mixture Shader and some other Issues with Corona and Team Render

« on: 2025-06-06, 12:25:51 »

Hi everyone,

I've been running into ongoing issues when using Team Render with Corona Renderer. The rendering behavior is noticeably different compared to local renders, and in this particular case, the Mixture Shader is not working correctly when rendered over Team Render. Locally, everything looks fine.

I've been using Corona since the early Alpha days (back when it was still free), so it's been around 8–9 years now. Unfortunately, I’m seeing more and more issues related specifically to Team Render.
Please also check my previous threads on this topic – I haven’t received any response there yet.

At our studio, we have six high-performance Team Render machines running locally, but due to the issues described, we currently can't use them. This seriously impacts our timeline and workflow, as we're now forced to render everything locally just to make sure results are correct.

I kindly ask you to take a closer look at this issue. We're definitely not the only ones experiencing these problems – and some of them have existed for quite a long time now. I always try to describe everything in as much detail as possible and provide clean test scenes to help track down the issue.

The current problematic scene is attached. I hope this can be investigated further.

Best regards,
Tuami

Team Renderer Issue with Corona Bitmap Shader in C4D 2025: Materials Not Display

Interesting. I had reported this Team Render issues a long time ago, maybe 4 or 5 years. Team Render behaves similar to Save with Assets. In my case, textures, at least from third party materials sets, when collected would change the name of the texture file to some random numeric name, but not the inside the path so they would all be missing from the render. In my case it was a material set from The Pixel Lab. I will try your workaround with a C4D node sitting in there.

For me, I haven't used Team Render in a long time, but this issue would be a problem if you want to use a render farm too.

I’m following up on this again. Just like with Tuami, we can reproduce the same behavior here.
Everything works as expected up to version Cinema Version 2025.0.2.
Starting with version 2025.1 and up to the current version 2025.2.1, files imported from the Asset Browser that either use the Bitmap Shader or are set up as Shared Materials no longer work in Team Render. Both V12-Hotfix 1 and V12-Update 2 work correctly under version 2025.0.2, but not from version 2025.1 onwards.
For us, this means we can no longer install any C4D updates, which is extremely inconvenient.

Hi @bnji,

I’ve discovered something interesting:
As long as the native Cinema 4D Bitmap shader is still loaded in the Node Editor (but not connected to anything), the scene works correctly with Team Render.
However, as soon as the C4D Bitmap shader is completely removed, it no longer works.

Could you please set up your scene like this:

1. Add the black & white opacity map to the Asset Browser.
2. Create a Corona Bitmap shader (make sure no C4D Bitmap shader is active in the Node Editor).
3. Drag the image from step 1 into the Node Editor and copy the asset path (IT HAVE TO BEGIN WITH assetdb:///) and paste it into the corona bitmap shader
4. Important: Delete the image you just dragged into the Node Editor, so that only the Corona Bitmap shader remains.
5. Connect the Corona shader to the Opacity input of the Physical Material.

Run a local test and a Team Render test.

Thanks!

Best regards,
Tuami

Hello bnji,

Thank you very much for your help in resolving the issue.

We are using Teamrender on Windows 11 machines with the latest version of Cinema 4D and the daily build, connected via a 10 Gbit Ethernet network, and the data is hosted on a separate server.

I've done some more testing, and in our case, we are using an opacity map. The issue occurs as long as no native Cinema 4D Bitmap shader with the same texture is loaded in the scene. Once the Cinema 4D Bitmap shader is loaded (it doesn't have to be connected to the material), it works fine. The problem seems to be specific to the Corona Bitmap shader (all paths are exactly the same). It appears that the Corona Bitmap shader has trouble when using Teamrender, with the data located on a server and loaded through the Asset Browser.

I'll try to provide a scene in the coming days.

The issue is still present in the current Corona daily build. The assets are stored in the Asset Browser and were created by us there. As mentioned, the setup worked both locally and with older versions of Corona. However, with newer versions, it no longer works over the Team Renderer, only locally. So far, we've only encountered this issue with this specific material, though it’s possible that other materials could also cause problems when using Team Renderer.

There seems to be some issue with the native Corona Bitmap Shader, the Asset Browser, and the Team Renderer. This combination appears to be causing the problem, as it works locally but fails when using the Team Renderer with newer Corona versions.

The issue does not occur with the C4D Bitmap Shader, but we almost always use the Corona Bitmap Shader. It seems that the problem arises specifically when using the Corona Bitmap Shader in combination with the Asset Browser and Team Renderer.

Corona Version 13 Daily Build – March 5, 2025

The Mixture Shader is not functioning correctly. When using blend modes, colors are sometimes not calculated correctly, leading to incorrect results. This issue was not present in the previous version.

Attached is a test file—please compare the results using both the old and new Corona versions.

Hi,

Any updates on this? The PSD files have become quite large, and now each file has CXR_Layers on top with gray noisy colors. We’re rendering via TeamRender, in case that helps narrow down the issue.

Thanks and best regards,

[C4D] Bug Reporting / Team Renderer Issue with Corona Bitmap Shader in C4D 2025: Materials Not Display

« on: 2025-01-09, 10:40:21 »

When using corona bitmap shader and materials from the Asset Browser and rendering with the Team Renderer, the materials do not appear in the final render. When using the interactive renderer it works. However, if the native C4D bitmap shader with assets from assets browser  is used instead of the Corona bitmap shader, it works as expected with team rendering. Is this a known issue? It also seems related to C4D 2025, as the problem does not occur in C4D 2024.

We use Cinema 4D 2025 and Corona 13 daily build. We export PSD files, and recently, there are CXR layers in the PSD file that are making the file huge. Is this a known issue.
Thanks

[C4D] General Discussion / Roughness Modus for shadow Catcher Material and AHA.io data protection question

« on: 2024-08-29, 14:38:32 »

it would be great if we could use the roughness mode in standard for shadow catcher material and posibillity to swtitch the mode in advanced tab like in the physicyal material.

btw:  i don't know if i have to make this request via the new ideas portal (aha.io) i'm not a big fan of this, and the very bright layout bothers me, but well.
. However, I cannot log in there with my chaos login data as announced in a forum post here. as TomG explains in his initial posting:

https://forum.corona-renderer.com/index.php?topic=43390.0

Furthermore, I do not believe that it is legal in the broadest sense to have this login information passed on to aha.io? Completely without a legal basis, however, the collection and transfer of customer data to third parties entails a data protection violation.

at the very least, consent should be given and it should be clarified how the data will be further processed with aha.io?
