Question Problem with submeshes

I have a mesh.
I split this mesh in multiple meshes along the Z axis.
The problem is that when I split a mesh with multiples materials the new meshes show only the first material (and the others are ignored), and I receive this warning on the inspector:


With a very huge drop of frame rate.
Someone can tell me what I should do?

 

Well, the error clearly tells you that you have more materials than submeshes. We can see that you have 17 materials. Are you sure your mesh has exactly 17 submeshes in total?

 

Every mesh has 1 submesh, but what should I do?

 

Well, when you split the submeshes into individual objects where each object has one of the submeshes, then each of those object needs exactly one material. Which one? Well, those which corresponded to the original submesh. The material list and the submeshes have a 1-to-1 relationship. So submesh 5 will use material 5.

 

When I split my mesh I create various meshes that can use multiples materials of the original one, and how can I add submeshes?

 

You can see examples of code for submesh manipulation here:
