Frequently Asked Questions
TRELLIS.2 4B turns a single photo (or text prompt) into a 3D mesh you can download as GLB, OBJ, or USDZ. Use the form above to upload your reference image and TRELLIS.2 4B returns a textured, downloadable model.
GLB (default — works in Blender, Three.js, Babylon, Unity), OBJ with separate MTL + PNG textures, and USDZ for iOS AR Quick Look.
Output is dense triangle soup, fine for visualization, game props, and AR previews. For animation-ready topology run the result through a retopology pass in Blender or use the /image/retopo/ tool.
Both. TRELLIS.2 4B produces a textured mesh — the GLB embeds the texture and the OBJ ships with a paired PNG + MTL.
TRELLIS.2 4B runs on our own GPUs. ~5,000 tokens per generation drawn from your daily free pool first; once depleted, paid packs start at $5 → 200,000 tokens.
Best on objects, props, and product shots with a clear background. Full-body humans are workable but limbs can fuse to torso on poses where occlusion is high. Headshots → avatar busts work well.
Centered subject, plain background, even lighting, 768×768 or larger. Background-removed PNGs give the cleanest meshes. The /image/background-remover/ tool feeds straight into here.
Yes — /batch/ accepts up to 100 source images. Each output lands in /account/?tab=history as a GLB with a download link.
Yes — POST your image to /v1/3d/generate/ with model="TRELLIS.2 4B". Returns a job_id; poll /v1/status/{job_id}/ for the mesh URL. /api/ has the full reference.
30 seconds to 3 minutes depending on the model. The close-tab-safe queue button on /image/3d/ lets you walk away — your result lands in /account/?tab=history when done.
Yes. Free.ai grants commercial use of generated meshes for game props, AR experiences, product visualization, marketing renders. You need to own the source image you uploaded.
Yes — failed jobs auto-refund. For "ran but looks wrong" results, email contact@free.ai with the share link and we will review.
