When I insert a block the textures change. In this case the original file has a bark texture for a tree trunk and a leaf texture for leaves. When I insert this file as a block into another drawing the leaf texture is gone and all the geometry shows the bark texture. How can this be repaired?
Can you post a 3dm of this mesh when the textures look correct and also one when it is a block and they don’t? If you can show the same issue with a smaller file or part of this one that’s fine too. Make sure to have the texture maps embedded in the 3dm with Save Textures checked when saving or post them as well.
The issue was resolved, although I’m not sure how exactly. When I saved the file as .OBJ the textures appeared in the block as they were assigned in the original .3dm file.
But because the .OBJ file was larger I worked further on the .3dm file to try and fix the problem. Somehow the issue was also resolved by purging extra textures/materials in the .3dm file, rebuilding the mesh, and assigning a different .png texture for the material.
