I have some GPU Render Issues when using Vray

Rendering V-Ray
1

When I want to render with Vray (07.10.02) in Rhino 8 (SR22
(8.22.25217.12451, 2025-08-05)) with my GPU (GeForce RTX 4060 Driver: 576.80) I get following error. I tried to render other files with my GPU and noticed that the error is coming when I use VisualArq (3.5.0.20135). Anyone hase the same Problem?

Error:
5.9.2025 15:55:33 Error [V-Ray] C:\GitLab\builds\UyPjKwLr\0\aec\appsdk-builder\cgrepo\vraysdk\s(1941) : CUDA error 700
5.9.2025 15:55:33 Error [V-Ray] [MemoryManagerGpu::releaseUnmappedMemoryFromInstance] 700: Could not release device buffer

Hi @Jesse_Altmann,

Why do you think VisualARQ could be related to this issue?
VisualARQ doesn’t use CUDA or any other GPU features, so in principle it shouldn’t interfere with V-Ray’s rendering process.

Could you perhaps share a simple example file where this problem happens? That might help us understand whether it is really linked to VisualARQ objects, or if it is just coincidental.

Hey,

you are right, I did some more testing and I cant find for sure if there is a issue with VisualARQ.

It seems to be a Problem with the lights from VRay Cosmos
