Spring RTS Engine

I have some texturing questions with upspring (not uv mapping).

- How can i rotate a texture (i only see a flip button)
- I have imported the textures right, but i cant put them on my moddel (they are all white and not visible ig). That works only if i have added texture A on the moddel with 3do builder and than when i m working with upspring i m only able to add texture A and not any other on the model.
- When i flip a texture, the texture is ig much darker than the other ones, why?

Or is upspring really that bad for the normal texturing?

I use 3dobuilder

UpSpring is really that bad for 3do texturing.

And you forgot:
- UpSpring show textures with up-down inverted compared to how it'll be ingame.
