@martinsiegrist I forgot one part. When using MeshSplit, it’s just a cached texture problem. They are a little too persistent in the WIP. You can use the RebuildMesh command with the PreserveTextureCoordinates option turned on, and it will fix it. We will fix this of course before ASAP.
Thanks for your replies Giulio. In Rhino 8 WIP I don’t get command line options for the RebuildMesh command.
I just tried to split the mesh in Rhino 7 both with MeshSplit command and MeshBooleanDifference. It works nicely. I also subtracted a Shrinkwrapped negative offset which I copy pasted from Rhino 8 WIP.
If I would have this rhino model 3D printed in full color in two halves, I’d want the outside of the mesh to be the real texture. The mating surface however I’d expect to have no texture just like the negative offset.
I subtracted a mesh sphere from my split rhino scan and here it works as expected.
