What is Trellis 2 3D Generation?
Trellis 2 is breakthrough 3D generation model with 4 billion parameters. This Trellis 2 system uses O-Voxel sparse voxel structure for instant transformation between meshes and latents. Trellis 2 employs Sparse 3D VAE with 16× downsampling to achieve exceptional efficiency. From 512³ to 1536³ resolution, Trellis 2 generates textured assets in seconds. O-Voxel handles open surfaces, non-manifold geometry, and internal structures without lossy conversion. Trellis 2 converts meshes in <10s on CPU and O-Voxel to mesh in <100ms with CUDA - fully rendering-free.

Trellis 2 Frequently Asked Questions
Learn about advanced 4B-parameter 3D generation model, O-Voxel technology, and production capabilities.
What makes Trellis 2 different from other 3D AI models?
Trellis 2 is a 4 billion parameter model using novel O-Voxel sparse voxel structure for 'field-free' 3D generation. Unlike iso-surface methods, it handles arbitrary topology (open surfaces, non-manifold geometry, internal structures) with instant bidirectional mesh conversion and full PBR material support.
What is O-Voxel and why does it matter?
O-Voxel is a revolutionary sparse voxel representation that enables instant, lossless conversion between textured meshes and compact latents (<10s CPU for mesh→O-Voxel, <100ms CUDA for O-Voxel→mesh). It's completely rendering-free and optimization-free, eliminating traditional bottlenecks.
What resolution and quality can Trellis 2 achieve?
Trellis 2 generates 512³ to 1536³ resolution assets with full PBR materials. On H100: 512³ in ~3s, 1024³ in ~17s, 1536³ in ~60s. Outputs include Base Color, Roughness, Metallic, and Opacity with up to 4096px texture maps.
What file formats and materials are supported?
GLB format with full PBR materials (Base Color, Roughness, Metallic, Opacity, up to 4096px textures). Also exports STL for 3D printing and OBJ for traditional pipelines. Alpha channel preserved but exported in OPAQUE mode by default (manually activate in 3D software).
Can Trellis 2 handle complex geometry like clothing or leaves?
Yes! O-Voxel technology specifically supports open surfaces (clothing, leaves), non-manifold geometry, and internal enclosed structures - breaking the limitations of traditional iso-surface fields without any lossy conversion.
How does Trellis 2 benefit 3D content creators?
Trellis 2 revolutionizes 3D workflows by reducing production time from weeks to seconds and slashing costs by 90%. Game developers, product designers, and digital artists can generate unlimited high-quality assets instantly instead of paying $500-$2000 per freelance model. Focus creative budgets on innovation while Trellis 2 handles rapid asset production with professional PBR materials and production-ready exports.
