MechaPaint
SketchUp is brilliant at form and famously casual about textures. Export your model, and MechaPaint turns flat color faces into painted surfaces, weathered wood, real brick, worn paint, ready for renders, Twinmotion, or a game engine.
Every tool unlocked. Exports are watermarked until you buy.
SketchUp exports arrive as dozens of components with automatic UVs at best. Combine + Unwrap merges them into one shared atlas and generates fresh UVs in a single pass, then you paint the building, not the bits. Turning dozens of components into one unwrapped object in a single pass may well be a first for 3D painting. Of course, that only matters because it lets you paint a whole facade in one go.
The pattern builder projects materials in world space, grain runs true along a beam and brick courses stay level around a corner, with no wrap seam. One click of the paint bucket fills a surface with the pattern.
The paint bucket floods an entire connected piece in a single click, walls, trim, panels, roof planes. Block in a color scheme for the whole model in minutes, then detail with brushes where it matters.
Clean models read as toys. Weathered ones read as places. Brush grime along the foundation, fade the paint under the windows, scuff the door, the hand-painted wear that makes a viz render convincing.
OBJ or FBX from SketchUp (built into Pro, and exporter extensions cover Free). Drag the file onto MechaPaint.
Run Combine + Unwrap if the model is in pieces, then flood-fill, pattern, and brush your materials on.
Export the mesh and painted PNGs together, ready for Twinmotion, Blender, a game engine, or straight rendering.
Buying unlocks watermark-free exports.
