Hello,

I’m using the latest V-Ray for UE 4.26. I have a scene with several 4K textures and I’d like to do a draft render on my dev machine. However, I’m facing out of memory issues when I try to render this particular scene.

I tried circumventing this issue by setting the Textures mode to ‘Resize’ instead of ‘Full’, however V-Ray throws an error both in CUDA or Optix render modes.

When I use CUDA, I get the following error:  
PTX build error 218, error message ptxas application ptx input, line 22; error : Illegal modifier ‘.uni’ for instruction ‘mov’  
ptxas application ptx input, line 22; error : Illegal modifier ‘.uni’ for instruction ‘mov’  
ptxas application ptx input, line 73; error : Label expected for argument 0 of instruction ‘call’  
ptxas application ptx input, line 73; fatal : Call target not recognized  
ptxas fatal : Ptx assembly aborted due to errors

And when I use Optix, I get the following error:  
[VUtils::VOptix::OptixModuleCreateThread::proc] OptiX error encountered in vray\_optix7.cpp[943]. Error Code 7200

The same errors happen when I try the ‘On-Demand’ mode.

Are there any workarounds or fixes for those errors?

Thank you.

Hi lee\_royling.

This seems to be a bug with the 4.30 core of V-Ray and I have logged it in. In the 5.10 core this doesn’t seem to be happening. Unfortunately there is no workaround that I can think of for the moment and there is no ETA when we will release the V-Ray 5 for Unreal for that fix ☹  
Is the problem only the 4K textures or could geometry be also an issue with this particular scene?

Best regards,  
Alexander

Hi Alexander,

Thanks for the reply. No problem, I decided to resize the textures manually from 4K to 2K. After that, I was able to render the scene successfully.

Best regards.
