Question Mesh with same UV divides it's materials and forces mesh to use two of the same material.

This is really hard to explain, but easy to show.

Import settings: Very typical for any imported model



But when actually in game:


What's worse is I can't actually just remove the material since each material is bound to different polys


And I don't believe it's a Blender issue, mainly because when I reimport it to blender and check the model, the affected polys aren't backfaces or anything really which could cause this.

Any help whatsoever would be greatly appreciated.

 

I'm not sure that I understand 100% but it looks like the chair is split-up into more submeshes then you need. So, for example, some of the orange triangles are in one sub mesh and some orange triangles are in a different submesh, but you're just assigning the same material to both submeshes?

When you open it in Blender, look at the materials tab and see if you have more materials than expected. Multiple materials assigned to the same object in Blender imports into Unity as multiple submeshes.

 

You're correct about the submeshes, it'd seems unity is turning single meshes into multiple. As for your suggested fix, it doesn't seem to work. Split the room model up into separate parts so it only has one material attached to each part of it and it's still deciding to divide up into submeshes

I guess the goal is then to try figure out why unity is making submeshes...

 

Just managed to figure it all out. Apparently, it's the "Keep quads" setting which is generating more submeshes. Thanks for the help ^v^
