How the Smart Topology Engine works

Choose one of your engine creations, a model from your library or a GLB from this device and import it to the engine — importing is free and private. Retopology rebuilds the mesh to a target face count: Smart keeps the silhouette and bakes the textures onto the new surface, Basic is a fast decimation, and Hold to compare shows the original. Restyle rebuilds a model as bricks, voxels, Voronoi pieces or a block world, and Repair parts closes the open geometry behind a split model's parts.

The Export lab converts to GLB, OBJ, STL, 3MF, USDZ and more, with texture size, scale, orientation, pivot and print-ready options. Each tool uses credits — the cost is on its button — and needs a free account (25 credits to start). For a free reduction on your own device, the 3D Studio's Optimize panel reduces polygons too.

Questions

What is the difference between Smart and Basic retopology?

Smart rebuilds the surface with clean flow to the face count you set and bakes the original textures onto it. Basic is a fast decimation of the existing mesh. Both let you compare with the original.

Why reduce a model's triangle count?

Real-time engines draw every triangle every frame. High-detail models look best close up; a reduced copy or a chain of LODs keeps scenes fast on phones, VR headsets and busy levels.

Can I 3D print the result?

Yes. The Export lab's print-ready option flattens the bottom and puts the pivot there, for STL or 3MF.
