Renders keep failing.

My renders keep failing. I’ve never had these issues before. I get a few different errors.

[09:33:23.138] Warning : Can’t modify renderer while asynchronously preparing to start rendering.

[09:33:23.139] Warning : Can’t modify renderer while asynchronously preparing to start rendering.

		\[V-Ray] \[VUtils::VOptix::AccelerationStructure::computeMemo ryUsage] 7001: OptiX error encountered in vray\_optix7.cpp\[2018]. Error Code 7001

​
I’m not sure what the warnings and errors are for. Can anyone help me decipher what these could be referring to?

I just had this error now.

I can render the scene using my CPU, but CUDA and RTX fail.

Hello calvin_ode,

Thank you for your report. Could you please send us the packed scene (Extensions > V-Ray Menu > Pack Project) via a support request, so that we can investigate the issues?
Please mention what is the V-Ray version you are using (you can see it in the V-Ray About window (Extensions > V-Ray Menu >Help>About).

Additionally, please make sure you are using the current recommended NVIDIA driver version for V-Ray GPU (currently 581.57) - V-Ray GPU | GPU rendering by Chaos .

Kind regards,
Iva

Hello calvin_ode,

We received your scene and investigated the issue. It turned out to be a known issue, which has already been fixed by our developers, and the fix will be included in the next V-Ray for SketchUp update.
As a workaround, disabling Displacement globally (Asset Editor > Switches) or disabling the Decal in your scene fixes the issue.

Kind regards,
Iva
