Polysurfaces too
Rhino keeps a render mesh with each polysurface and extrusion. MechaPaint reads those, so your NURBS model opens as a paintable mesh with no Mesh command needed first.
Rhino 3DM + MechaPaint
Rhino files, read natively. Meshes, and the render meshes inside polysurfaces and extrusions, open as paintable parts by layer.
WHY MECHAPAINT
From Rhino to painted without a mesh export
I built an openNURBS-format reader into MechaPaint. Open a .3dm from Rhino 3 through Rhino 8 and the mesh objects, plus the render meshes Rhino stores inside every polysurface and extrusion, come in with their UVs, named by object and grouped by layer, at the file's units.
Layers and names kept
Objects keep their names, layers become groups, and material assignments carry across, so the model is organized the way you left it.
Units respected
Millimeters, inches, feet, or meters, read from the file settings, so the model arrives at its true size.
Export anywhere
Paint full PBR and export FBX, GLB, OBJ, or STL for KeyShot, Unreal, Unity, Blender, or your printer.
PIPELINE
Three steps
01
Open the .3dm
Drag it on MechaPaint. Save from Rhino with render meshes included, the default.
02
Paint
Layers, masks, symmetry, the clone stamp, Mecha Lines, decals, and the full PBR channel set, painted straight on the model.
03
Export
FBX, GLB, OBJ, or STL with the painted maps.
Rhino models, painted like products.
