Check this file exists. Take note that venv makes hard link to file. If it exists, try reinstalling custom_rasterizer

I have also encountered the same problem. How can I solve it

Hi.
I have ComfiUI portable v0.3.49;
Python 3.12.10;
CUDA 12.8.0.

I get an error when the worker process reaches the Hy3D21MultiViewsGeneratorWithMetaData node.
ImportError: DLL load failed while importing custom_rasterizer_kernel: The specified procedure could not be found.
I've followed all the installation instructions in the guide and searched extensively online. But I can't fix this error. I really need help, please!

I think the provided wheels in the dist folder only work with cuda 12.6
I also have 12.8 and getting the same error. At the same time I'm unable to build it manually

You will have to create a version for the current installed cuda version.
Luckily this is rather simple to do, simply follow the steps from the guide to install the custom node as before, then follow these steps:

I'm running this on windows with the comfyui portable installation, So for linux you'll have to change the python call but otherwise it's the same. Make sure comfyui is not currently running or it can't overwrite the previous wheels (if you already used the distributions from the installation instructions).

Go to your comfyui install and then to the following folder: ComfyUI\custom_nodes\ComfyUI-Hunyuan3d-2-1\hy3dpaint\custom_rasterizer
Open a console in this folder and then run this:
"../../../../../python_embeded/python.exe" setup.py install
This will build the custom_rasterizer for your current python with whatever cuda version you have installed and move it to the packages.

Do the same for the DifferentiableRenderer here: ComfyUI\custom_nodes\ComfyUI-Hunyuan3d-2-1\hy3dpaint\DifferentiableRenderer

After doing both of these I was able to run it on 12.8 just fine.

You will have to create a version for the current installed cuda version. Luckily this is rather simple to do, simply follow the steps from the guide to install the custom node as before, then follow these steps:

I still got this error even after compile
and now after trying to reinstall pytorch for cuda 12.9 i got RuntimeError: Error compiling objects for extension

How to make it running on 50xx series

Please help
