3D Gen Studio setup: ComfyUI and Trellis 2 workflows

Philip from Pixel Artistry walks through 3D Gen Studio, an open source desktop app that connects to an existing ComfyUI installation for local AI 3D workflows. He demonstrates the Windows installer and points to Mac DMG and Linux AppImage downloads. Setup includes selecting the ComfyUI folder, downloading models and installing workflows. ComfyUI must run in the background, and each workflow needs its dependencies installed separately.

The tutorial follows a character through image generation, background removal, Trellis 2 mesh generation, retopology and texturing. Philip shows how to expose a background-removal Boolean in the Trellis 2 preprocessing node to address an error he encounters. He also compares the Kanban project layout with the node graph, where branches can hold multiple views, separate character parts and variations.

The demonstration uses an Nvidia GPU; Philip says there is no AMD solution for this setup at the time of recording. He notes texture flaws and a flickering, laggy graph viewport. Optional Tripo AI API use requires a key and billing credits, so that route adds an external service to the local pipeline. The final walkthrough covers sculpting, non-manifold edge repair, watertight checks, automatic retopology and UV generation in the mesh editor.
