Hey there
I have a problem when I try to use CUDA or GPU for rendering
I get these errors a lot “attached photos” especially the one that says “could not initialize the GPU for rendering”
even that sometimes it works
like literary the same shot with the same setting did successfully render the first time but when I tried to rerender it I got these errors
I use Revit 2022 - 51020 and Geforce RTX 3060
I hope you can help me with this issue
thanks a lot in advance
It looks like you’re running out of memory. How big is your scene?
Is that hybrid rendering or GPU-only?
I don’t think so
I use GPU Geforce RTX 3060 which is 12 gb
27" monitor
and tried both
GPU only or Cuda hybrid
both not working
only CPU rendering working but it takes really very much more time to render with it than the hybrid
We’ll need to look at the problematic project then, and attempt to reproduce the issue on our end. Will you be able to share the project + all accompanying assets with us?
ok I can share
it’s kind of an unfinished huge project though
it could be because of the size of it
not sure
One more thing before sharing it though. Can you make sure you’re using the latest drivers? (This should be checked on NVidia’s official website: Download The Latest Official NVIDIA Drivers)
If not, you need to update the drivers.
Another thing → what did you do after you received the error? Have you attempted to restart Revit? You need to.
yes I already checked and I’m sure I’m using the latest drivers
also, I did try restarting the Revit and restarted the whole PC
didn’t fix the problem
We’ll then need to test the project.
I sent it to you in a message
Hi again @arch_mado ,
Please, try the following:
1. Close Revit
2. Find the VRayPlugins.json file located in C:\Users\<your username>\AppData\Roaming\Chaos Group\V-Ray for Revit 2022
3. Open the file with a text editing program (f.e. Notepad)
4. Find the following parameter: OpenclResizeTextures which is set to 0
5. Set it to 2
6. Save the file
7. Open Revit and render
Best,
Ana
ok here is how I fixed it
I found that the problem is the memory for the fur as it’s a big project with kind of wide green areas
so when I turn the fur off, the Cuda or GPU rendering works fine
it appears that I had too much amount of fur
so I reduced the “count/area” and it worked fine
Hi there,
I have the same problem. Trying to render a very easy scene (70MB), using double sided material. It would give me “could not initialise GPU for rendering”. It would work with CPU only.
Hello francesco_salvatori, could you please share the following details:
Additionally, if possible, please share the project file that is causing the problem, You can upload it here or, if you prefer, you can open a ticket and share it directly with us.
