VRAY7 GPU rendering crashes

[123456_]

I uploaded a max file and exported it to VRScene using max. However, when importing it to C4D and rendering it using GPU, it would crash directly. The previous VRay6 did not have this issue, and I also uploaded a demonstration video of the problem

Dear 123456_,

I've reviewed the 3ds Max scene you provided and found several factors that are likely contributing to the issue:

• Missing Material/Map - This might be caused by materials or maps from a not available render engine
• mental ray attributes
• Empty Bitmap Files - a significant number of materials in the scene reference empty bitmap files
• Deprecated features - Irradiance Map, some materials settings

I performed a test by removing all the materials from the file. After doing so, the issue no longer occurred, confirming that the root cause lies within the materials in the 3ds Max file.

To resolve the issue, I suggest:

• Clean up any materials with empty bitmap references
• Remove unsupported maps and missing plugins
• Switch from Irradiance Map to Brute Force

Please let me know if this works for you.

Maybe it's like you said, but the same file can be rendered normally in VRAY6 on C4D, so I think it may be a problem with VRAY7

Dear 123456_,

After further investigation and discussion internally, I can confirm that this will be addressed and fixed from our side [VC4D-2602]. I will notify you when the fix is ready.

As a temporary workaround, you can delete the shader from the light material in your scene inside Cinema 4D. This should allow you to render the scene without encountering crashes - see example.
In addition, I recommend optimizing the original 3ds Max scene as mentioned in my previous message, to avoid potential issues.
