I have a problem while trying to modify the OBJ file in Rhino. It is a file showing the terrain model with ortho images as textures (>10 of them). I want to add some objects (raised lines on the terrain) and then have it 3D printed in full-colour. The issue is that when I export the modified file, it has no textures. I tried to modify the MTL file manually without success. The texture files are in the same folder as the exported OBJ.
I will upload the necessary files but have to know first, what do you guys need.
Do you have any ideas what might cause this problem? Is there a problem with import/export options or the file structure?
Thanks in advance!
