The author shared their complete process of successfully running Hunyuan3D's Custom Rasterizer in a Windows ComfyUI Portable environment, summarizing various installation pitfalls.
Major Pitfalls
- MSVC / CUDA version conflicts: Compiling customrasterizer triggered Visual Studio incompatibility errors. It requires syncing environment variables and ensuring CUDAHOME points to the correct CUDA Toolkit (the author used v12.6).
- Missing dependencies: Running Hunyuan3D requires a full suite of AI packages, as well as modules like pymeshlab and transparent-background.
Installation Steps Provided
- First, use embedded Python to install dependencies like diffusers, transformers, accelerate, safetensors, sentencepiece, huggingfacehub, and xatlas.
- Next, install pymeshlab for mesh post-processing support.
- Finally, install transparent-background to ensure the background removal node in ComfyUI Essentials works properly.
Final Results
- ComfyUI launches without import errors.
- The entire process took 119 seconds to complete.
- Hardware used: RTX 3090 24GB.
- The output is a clean 3D mesh complete with UVs and textures.
