Have you solved it? I have this problem too?

[criskb]

i have this aswell

Hi, may I ask you which method did you use to install this tool? (Embed env with pre-build wheels or Miniconda), Also where and how did you download this package? Because it should be ComfyUI-3D-Pack_init_.py instead of ComfyUI-3D-Pack_init.py

[crowtalons]

same here. embed env with wheels. I have correct init.py filename but the same exact error:

okay turns out I'm a dumbasss and did not have VS build tools. downloaded those, re-installed the addon and it works. hope maybe that helps someone else as well.

Hi crowtalons, which Visual Studio tool did you install that made the difference? I have the same error message and checked my VS and couldn't find any build that was missing...

[crowtalons]

@Scharwunzel it was the one mentioned on this project's page: https://visualstudio.microsoft.com/downloads/?q=build+tools I downloaded the community version (as mentioned, installed with Workloads: Desktop development with C++), I don't recall the exact settings I selected when installing, but if I figured it out, you should be fine 😁

[Scharwunzel]

@crowtalons, thank you very much for the quick answer. I already had VS on my computer before Stable Diffusion or comfyui, and C++ was already installed. I also updated everything and looked through the individual builds. So that can't be the cause of the error for me. I'll open a new thread about this, I don't know what else to do. Kind regards
