So, what do I need to get started?

[TheDarkerSideofYourShadow]

I would like to use some custom/altered models in one of my maps, as well as some custom textures. This means I need to start making some stuff

I would just like to know, what kinds of software (or other things) will I need to get started? I've heard GIMP/PS for textures, and then Maya/3dsmax for models. I also remember hearing that, for models, you have to mess around with one of the items in the SDK.

Alrighty, thank you :-D
