BD Pixal3D Image to 3D
Generate 3D from image using Pixal3D (Trellis2-based pixel-to-3D). Downloads TencentARC/Pixal3D model weights (~10GB) on first run. Model is cached at $HF_HOME (/srv/AI_Stuff/models/huggingface/). Pipeline types: - 1024_cascade: Standard quality (recommended) - 1536_cascade: Higher geometry and texture resolution Outputs: - mesh (TRIMESH): Untextured Z-up geometry. Feed into BD_CuMeshSimplify or BD_BlenderDecimateV3. - voxelgrid (TRELLIS2_VOXELGRID): Full PBR voxel data. Feed into BD_OVoxelBake for sharp-edge-preserving texture bake, or BD_OVoxelTextureBake for bake-only.
