V-ray could not allocate buffer

I have produced one render already today, but now V-Ray has completely stopped working. I have no idea what to do.

The errors:
[16:36:49.821] Error : [VUtils::SimpleGPUBuffer::init] 2: Could not allocate buffer of size 0MB!
[16:37:32.185] Error : [VUtils::VOptix::ContextImpl::buildAccelerationStructure] 7001: OptiX error encountered in vray_optix7.cpp[3041]. Error Code 7001
[16:37:32.348] Error : 2: (0) : CUDA error 2 : unable to allocate enough memory to perform the requested operation (out-of-mem)

Please help!

I mean this should be directed to Vray support but what does your Rhino SystrmInfo show?

Hi,

First your graphics driver is newer than the verified one. V-Ray is built against given version of the nVidia driver API. Newer APIs may introduce instabilities or problems. Chaos verifies each driver release against some internal tests. If the driver is newer than the last verified - use it on your own risk.

Second - there seem to be insufficient memory on your graphcs card to render the scene. Either

  • try to reduce the complexity (fur, displacement, texture size and/or compression, etc);
  • try to reduce the GPU load (eliminate additional running software that takes up GPU memory)
