Hi there guys...

I have this problem where when I try to save my drawing after putting the shading and textures on my landscape... What happens is that I still am in the shading window and when I get the result that I want and try and save, it changes all my lamberts to the same one.... meaning my Grass, mountains and river all become my river.... all of them change to the same one...

I'm still new to this program and don't know what I'm doing wrong...

Can someone pleeeeaaassee assist me in correcting my mistake
