I'm importing .blend file into unity. The file contains 9 separate objects. Now all objects have the same 2 materials assigned. When importing in unity one object's material slot is reversed. But in blender I set the slots correctly.
This is only happening for one object (Curve.076). This is important for me as I am assigning the material from code to each slot. Here's the .blend file if you want to look at it. Download
Okay so playing with the object for some time I found that the problem is with only related to one face. In the picture below see the white face between blue faces, if leave the face like this than the slot in unity is not reversing. But if I assign the face to the inside.004 material than the slots are reversing. I tried delete the face and again filling the area. But same result. I have to make the face same material as the upper part to not get the problem, which I don't want. Only work arround I can use currently is that extruding the face little forward and assinging the material to it, which is not very neat. I might be missing something as I am not very good at blender.
