It seems you are running out of VRAM. Try monitoring your memory usage with a third-party software such as GPU-Z to see if that is indeed the case. If not, send the scene to support@chaosgroup.com so we can take a look. Mention this thread, along with your V-Ray and host platform versions.
If so, you would need to optimize your scene. Here are some tips:
1. Use “On-Demand Mip-Mapping” for textures (in critical situations you may need to Resize the resolutions)
2. Optimize dynamic geometry. Hair/Fur, Displacement, and Subdivision objects tend to consume a lot of memory, especially when rendering high resolution images. Make sure the geometry generated by them is with acceptable quality, but reasonable polygon count. I.e.decrease subdivisions and displacement edge length.
3. Use V-Ray Proxies
4. Remove unnecessary/out of camera view objects (If they are not specifically needed). It’s not uncommon to have a project populated with lots of unneeded or not in camera view objects.
5. Optimize regular geometry. Very often objects with unnecessary dense geometry end up in the project, those are usually assets gathered from external libraries.
6. Export to .vrscene and render with V-Ray Standalone - this way you may save a bit of Vram from the host application
7. Close other Memory Intensive applications
Hello Aleksandar,
Thanks for your reply. Will check for the suggestions.
