Why wont the model show up in game?

[Cat_Man9000]

I have a quadcopter part thats basically a probe core with 4 attachment points and it works fine except the model doesnt show up so i cant select it. Ill upload a few pics here

Also how do i 'assign KSP shaders', i cant find any ksp shaders other than the particle shaders

also also what is the 'File URL' in the Part tools script

Ok for anyone who has the same problem, combining all the textures into a single one should fix it (at least for me it did)
