Switching a texture on a model with multiple materials?

How do I go about changing one of the assigned materials on a model? I'm trying to lower the number of materials I'm using and it's proving tricky.

It is pretty tricky! You have to figure out what textures are attached to what materials and just get rid of any extras that don't have special purposes like glow flags or something of that nature. To replace a material on a specific region you'd select the polygon cluster and assign the new material to that cluster.

alt +7 is the correct window i think. Not sure, since i didn't worked with XSI for a long time. You can see all materials there and the context menu gives you the options select assigned polygons and assign to selection. I don't think i need to explain further how to go on

Close! It's actually CTRL + 7! ALT + 7 is for UV edits!

You can also use a hex editor. Each material is a MATD chunk. The first MATD is assigned 00, the second MATD is assigned 01, and so on and so forth. Each cluster is a MATI. The fifth place over from MATI is the value that corresponds to the MATD number.
