Really thank you guys, Flipping the normals I have solved the problem!! :D Thank you guys, that really helped

When I try my nwe items in dota 2 workshop they appear like if the texture was inside the modeling or something very strange as you can see in the picture:

If anybody can tell me how to fix this problem I'll be so glad, I dont know what to do and obviously this is not as it should be. I did the textures and the modeling the right way cause it compiles by the way, so I dont know where is the problem :(

If anybody can help :) thanks guys!! (sorry for my bad english)
