A friend of mine asked me to make him a model for D3 Deathmatch, the model is done, but he showed me like 4 or 5 different textures for one of the game models. So I guess my questions are: What are the _local textures used for and how do I make them in say Photoshop 7? What are the other textures used for? Besides the main texture... I looked at the links in another post, but I couldn't find what I was looking for. Could someone help me with this? P.S- I use 3ds max 6 for my modelling and photoshop 7 for texturing.

_local is the bumpmap, or normalmap. Simply put, this is what allows you to do fine details (scratches, bumps, grooves, etc.) and cut down on polycounts. You can make them in PS7 using Nvidia's Normalmap Authoring Plugin. However, the best way to get a nice normalmap is to use renderbump. Basically, you create two versions of your model: A hi-poly and a lo-poly. The hi-poly is used to create the renderbump. That model has the actual scratches, bumps, etc. designed on it using polies. The renderbump from that model can then be wrapped around the simplified lo-poly model, giving you a nice-looking model without sacrificing performance. I highly recommend reading up in Doom3World.org's Texture Creation Forum before messing with texturing. You will encounter so many things that are very good to know about the engine there. If you do end up creating your normalmaps using PS7, I recommend reading Kat's article at Q3Bits about using heightmaps to make your normalmaps look better (mainly for photosourced textures)

Wow! Thanks, Snoop! I didn't realize there was so much involved. That is definately a major help.
