Mesh export with Textures/Materials?

[MisterBananaPants]

Total noob here. Workflow to Rhino 7.

I've been supplied with .e57 files
I've saved out meshes as both DXF and as OBJ (tho would prob prefer an OBJ workflow ultimately.)
When I import the mesh file into Rhino, it has no related material connected to it.

How do I keep/re-apply the originating PoinbtCloud's material/texture on the exported Mesh?

Thx

So e57 files contain points and (optionally pictures).So I guess you create a mesh out of these point clouds? (with Poisson Reconstruction?) And then export this mesh to DXF or OBJ?

The issue is then that:
- DXF is too basic and it doesn't support per-vertex colors or textures
- OBJ doesn't support per-vertex colors either! And CloudCompare cannot generate a texture from per-vertex colors...
