My model has in-side out textures

I made a model, and all was going well (except for some skeleton problems). But when i actually put the model into source and looked at it the textures were inside out. I could see the textures on the other side of the model but not the ones on the side i was looking at.

picture:

The model shows up fine in 3ds max with the textures but i don’t understand why it shows up inside-out in source. Does anybody know how to fix this?

Your normals are inverted. Try adding a Normal modifier.

Ty that worked!
