# trellis-mac — TRELLIS.2 MPS/Metal port (local SOTA image-to-3D). Its setup.sh
# creates its own .venv (py3.11), clones the mtl* Metal-kernel deps, and builds
# them. Gated HF models (facebook/dinov3-vitl16-*, briaai/RMBG-2.0) download at
# runtime — the owner must `hf auth login` and request access (usually instant).
