The mesh has no material, but is using a material.

newmodels

I learned how I could make unique colors for the nodes in code. But when I try to get the material using get_surface_material it returns null. I looked at the mesh in the inspector, and it's not set. How is godot still coloring the mesh if the material is empty? How can I get that material without having to set them in the node inspector.

I found out that the material was attached to the a mesh. ImeshInstance.get_mesh(). then that material can be gotton with surface_get_material(). But duplicate() and setting the material has no effect. Other than changing the color of all of them. I tried duplicate on the mesh and still all same color. I tried duplicate(true), and nothing was different. I tried setting the material to the meshInstance, but it didn't do anything.

It worked. I can now have custom colors. Both the mesh and material must be made with duplicate(). Get the mesh with from the MeshInstance with get_mesh(). Duplicate that mesh Then get the material from the mesh and duplicate. change the albedo_color for the new mesh. Set to the the new mesh. And then set the mesh to the MeshInstance.

Both the mesh and material have to be duplicate. Then assigned. Both the mesh and the material is a shared resource. Most efficient on ram I agree. But godot didn't give a way to have custom coloring.
