Apple M2 install errors for custom_rasterizer and differentiable_renderer

[Snake-Konginchrist]

Following the official Hunyuan3D documentation to install dependencies on Apple M2 (macOS, arm64, Python 3.12, PyTorch MPS), I encountered the following errors:

1. Installing custom_rasterizer: OSError: CUDA_HOME environment variable is not set. Please set it to your CUDA install root. → Cannot build on Apple Silicon, requires CUDA.

2. Installing differentiable_renderer: clang++: error: invalid argument '-bundle' not allowed with '-dynamiclib' → macOS compile flags conflict.

Please clarify if texture generation supports Apple Silicon (M1/M2), and I would appreciate any guidance on fixing the macOS build flags for differentiable_renderer.

这是典型的Apple Silicon（M1/M2）暂时支持问题和编译工具链冲突的问题，可以寻找下解决方案。如未解决，欢迎私信：2562367495 请注明来意
