Objects with more than one texture

[Theforgot3n1]

No one seems to have addressed the way the textures are dealt with in Amnesia. Trying to decipher it, for static objects, it seems they use this .dds, most likely consisting of the details of it's properties, and the .mat. This .mat file often has like a bunch of segments of textures in it that are used by several objects.

I just opened a thread regarding how to import a model with a texture that spans the entire object. It was fairly simple. But attempting to make a complexer one with a few more textures seems to require a lot more to do... SO HERE I AM!

How would one go about creating an object that, for instance, has a protrusion using a different texture than the main body (especially curious about the .mat file/material editor).

Thanks in advance. There's a lot to do before I can successfully use some custom models though. :-(
