Unity creating materials out of thin air - Resolved

[raidernick]

I am having a serious problem importing a mesh into unity. I can import it as a blend file or fbx it doesn't matter. Unity is "creating" random materials out of thin air for the objects. All of my objects have the material aura_panel. There are NO other materials in blender at all. Every object is linked to this one single material. When I import into unity it is inventing these random materials I've never seen before and applying multiples of them to each object. If I set the object to have only 1 material size in unity it makes part of the mesh invisible, so this isn't a solution I can use. I am dumbfounded as to why this is happening.

Am I right in thinking that the first shader is what you set up and the second shader was generated by Unity? Regardless, have you set your shader(s) to KSP shaders instead of other Unity shaders? I don't know if that will solve the situation as I'm not trying to experiment with Unity at the moment. Good luck!

Here's the Blender manual on Material Slots: http://wiki.blender.org/index.php/Doc:2.6/Manual/Materials/Multiple_Materials

Basically what you're seeing is some parts of your mesh are assigned to a second material slot, so without that second material those faces won't render. I ran into this problem a while ago but it's easy to fix.

That would be true if they were, but they aren't. I made sure I looked at every object. They don't have empty materials assigned to them.

I was able to resolve this by creating a new file in blender and appending this to the new file without bringing over any textures or materials. I then recreated the materials and textures and imported back to unity.

if only one vertex is assigned to an other UV, you will have this result - blender will NOT display a second material slot

when you redid the texturing, you where more precise with UVs, problem solved..

still, it's what OrbitusII said..
