Thanks Mike - that makes life a LOT easier I wonder If you could help me out here, because I'm struggling with textures and so-far no-one has answered my posts on ther matter...
This was my last post....

I hope someone can help me out here because I have been trying to create decent looking texture(s) for my Level.
I'm especially having problems with mesh type ones or the 'walkway' type of stuff - like in Unreal. where there are just raised bumps so you don't slip. Are there any tutorials for Photoshop that shows how to do grills/mesh's etc?

And the 'alpha' channel... Is that for creating these bumps, in a bump-map? (And do I need one to create a 'glass' texture?) I'm just about to try learning how to create them in Photoshop, some basics would help a lot..
