Rhino 7 Vray GPU interactive render not showing resized textures

V-Ray V-Ray GPU Issues

Hi, I’m having an issue whith vray interactive render (GPU mode) not updating in real time new texture mapping sizes, changes do appear every time I stop the render and re render again but the point of using interactive render is to show instantly the changes.

In this first image i have the XYZ size set to 1

And in this second image I changed the values to 5, 3 and .2 but the interactive render is not applying those changes :frowning:

Do someone know why is this happening?
(i have an RTX 2060 super)

Dear @bruno_villarreal , hello.

The orange dot is signing warning in you V-Ray Log (VFB’s right wing). Could you take a look and share what exactly is?

Maybe is this one ```
Warning : Max sample level set to 0 - rendering could take longer than expected. Consider setting a value to decrease the render time (i.e. 10000).


Could you confirm that the change is only applicable when RTX is chosen and V-Ray Interactive is ON?
From my tests when CPU or CUDA are used as Render Engine, the changes are visible in Interactive without the need of re-rendering in Production mode.

Waiting for your answer.

Best regards,

Hi @tsvetomira.girginova thanks for answering. Yes the Vray log is giving me that exact same error.

Also I can say that this only happens with Interactive Render for RTX ON, when I use the CPU or the CUDA mode they work and scale the textures perfectly.

Thank you too!

I have just logged this in our system with VRW-3760 number for further investigation.

Two things more:

  1. When V-Ray Interactive is on RTX, you are still able to manipulate the texture from V-Ray Asset Editor (UVW Placement/Texture placement of the used texture)
  2. As shown at the log you are using now newer than the recommended drivers. Keep in mind that except in the V-Ray log, this information is published also here

For now please use CUDA (all variations = CPU / CPU+GPU / GPU only) or CPU for V-Ray Interactive if you want to test changes through Rhino properties.

And I will keep you posted by any news.

Thanks! tsvetomira.girginova hope the gpu team will fix this problem soon. :smile:
