Missing lib folder in custom_rasterizer - cannot compile CUDA extensions

[dre2rd]

Description

I'm trying to install the Hunyuan3D-2.0 components following the installation guide, but the lib folder with CUDA source files is missing in scripts/hy3dgen/texgen/custom_rasterizer/.

Steps to Reproduce

1. Clone the repository:

   git clone https://github.com/Inception3D/Motion324.git
   cd Motion324
   

2.Try to install custom_rasterizer:

cd scripts/hy3dgen/texgen/custom_rasterizer
python setup.py install

Expected Behavior

The lib folder should contain:

lib/custom_rasterizer_kernel/rasterizer.cpp

lib/custom_rasterizer_kernel/grid_neighbor.cpp

lib/custom_rasterizer_kernel/rasterizer_gpu.cu

As referenced in setup.py (lines 8-11).

Actual Behavior

Error during compilation:

c1xx: fatal error C1083: Cannot open source file: lib/custom_rasterizer_kernel/grid_neighbor.cpp: No such file or directory

The lib folder does not exist in the repository.

Environment
OS: Windows 11
Python: 3.11
PyTorch: 2.4.1+cu124
CUDA: 12.4

Questions

1. Are the CUDA source files in lib/ folder supposed to be in the repository?
2. Should they be downloaded separately or generated automatically?
3. Is there a workaround to use Motion324 without compiling these components?

Checked

• ✅Tried git submodule update --init --recursive - no submodules found
• ✅ Verified .gitmodules file does not exist
• ✅ Checked GitHub repository - lib folder is not visible in the file tree

Really thank you for reminding me of ignored files in Hunyuan2.0 part. I have added them and tested scripts successfully in a new environment.
You might encounter assert error in check_torch_load_is_safe when loading Hunyuan2.0, which require users to upgrade torch to at least v2.6. To bypass this, you can simply comment out that section.
