Please see the attached as I cannot explain what is happening in words.
Textures are jumping to different objects.
This file was created in Vray 6.1 (last version) and Rhino 7.
About a week ago I updated to 6.20.01 hotfix, and found this problem after working 40+ hours on several projects.
Different files all created with Rhino 7 and Vray 6.1, the result is the same.
It might be related to lightmix.
What happens if I rollback to Vray 6.1, to all the files I worked on with Vray 6.2?
I have done about 40 hours of work, is that now lost?
I am getting files together to send to tech support, but I need IMMEDIATE feedback please.
Thank you,
Glenn
Hi all,
The problem occurs with GPU rendering, specifically with On-Demand Mipmapping enabled under V-Ray GPU settings. This problem has been identified and reported to the Development Team (VRW-4304). We will keep you updated when there is more information.
In the meantime, you can consider the following workarounds:
- Render using the CPU instead of GPU.
- Set the “Texture Mode” in V-Ray GPU settings to Compressed textures
Thank you for your understanding.
