Yumi3D 1.5: cleaner models, sturdier files, and new colors for the season. • Mesh Cleanup, rebuilt for professionals: finds and fixes 16 kinds of mesh problem, up from 7. It now covers overlapping vertices, zero-length edges, collapsed, doubled and lamina faces, non-manifold edges and vertices, flipped and inside-out shapes, T-junction cracks, holes, n-gons, and concave, bent and twisted faces. • Every problem is explained in plain words. Select shows them on the model; Fix repairs one kind, or Fix All repairs everything as one step you can undo. • Fixes keep your UVs, seams and creases. Collapsed faces are removed without leaving holes, and n-gons become clean quads without touching the rest of the model. • Many-sided and dented faces now always display and export correctly. • Five new color schemes: Harvest and Cranberry for fall, Evergreen and Frost for winter, and Graphite, a tint-free grey for judging texture colors accurately. • Sturdier file handling: damaged or malformed project, model and image files are now refused safely instead of closing the app. • Many smaller fixes and improvements.

Yumi3D 1.2 is a big one. • Materials and rendering: colour, roughness, metal, glow, glass, clear coat and subsurface, with presets. Ray-traced renders and a live ray-traced preview, depth of field and motion blur, and full-HD videos. • Game-ready tools: Check Game-Ready finds problems and fixes most of them in a tap. Bake normal and AO maps from a high-poly sculpt, make LODs, and export masked transparency to GLB, USD and FBX. • Decals and Face Cards: stamp decals onto a model, and lay painted anime-style eyes, brows and mouths onto a head as cut-out cards that follow a rig. • Simulation: smoke, fire and liquid, cloth that falls and collides, and spring bones for hair, tails and scarves. • Animation: takes and layers, constraints and drivers, and motion capture (BVH) retargeted onto your rig. • Modeling and sculpting: the Tube tool, custom brushes you can save and share, and Remesh that keeps close parts like fingers separate. • Projects: Versions keeps snapshots you can go back to, the Library holds your assets, and Learn has step-by-step tutorials. • The File menu is regrouped so it fits on every screen, plus many fixes and speed-ups.
