Multiple Mapping channels for UV Editor in Rhino 5/6

You should be able to export your CAD data… Blender.

We usually refer to a CAD file to IGES extension capable of exporting NURBS or surface.
Blender does not allow you to import IGES surface. So you need to create the mesh in Rhino. Instead, that particular software is capable to convert automatically your CAD (surface) into a mesh (including LOD) and unwrapped without al the manual process involved.

My workflow for UDK Unreal Unity, etc… is to first unwrap in Rhino the polysurface,

[FEEDBACK] V7: Joining surfaces does not lose its individual texture mapping unwrap

At the moment the only solution i found was to export the meshes as FBX to Blender. Then “join” them there and return back as OBJ. Since Rhino export beautiful and perfect custom vertex normal maps is better to preserve them across the workflow. Blender FBX exporter is applying vertex normal recalculation that change the final vertex normal. Blender OBJ exporter is working well for vertex normals.

then convert to mesh using Grasshopper for inspecting better the final result dynamically and accuracy instead of just using the command.

Export to Blender as FBX and join there the meshes.
Also, prepare the final UV mapping and material before Painter.

How to paint Rhinoceros FBX from Rino3D to Substance Painter workflow

The process for a good rendering or game object is long. Rhino is one of the best tools for creating hard-surface. Is possible to paint the final product in Substance Painter, but Rhino is still not a good friend tool for the final unwrapping triangle polysurface model (unwrapping). Also converting into mesh quads or triangles is a bit overcomplicated full of unexpected results as for example, not align triangles, holes, etc. Still, Rhino can be a very good option and here is a draft copy of my…
