Tencent ARC releases pixel-aligned Pixal3D

Pixal3D solves the "hallucination" problem in 3D generation by grounding geometry directly in the input's coordinate space.

• –Pixel back-projection lifts 2D features into 3D volumes to ensure 1-to-1 fidelity with the source image.
• –Integrated with TRELLIS.2 for superior coarse-to-fine geometry and PBR texture synthesis.
• –Capability for object-separated scene reconstruction allows for extracting clean assets from single photos.
• –Exports to GLB, OBJ, and USDZ make it immediately usable for Unity and Unreal Engine pipelines.
• –Currently limited by an academic license and high GPU requirements (RTX 4090+ recommended).
