I tried to change my shaders for my character because Unity imports OBJ without bumpmaps/normalmaps. First everything went ok. I changed the shader to diffuse/bumped, then i changed the textures. But at one point the texture slots vanished. And they stay vanished in this project when i reload it. I can load another project, and there i have my textureslots back. But in my own projects the texture slots misses.
What goes on here? How can i get the slots back?
