hi! as of late i've been interested in creating a custom model for postal 2 to replace the postal dude with something closer to how he looks in the concept art for the original game, but i'm not entirely sure how to go about this. i'm mainly concerned about what program i should use for the modelling and texture work, since i don't know if that's possible within the postal 2 editor itself, or if i need to use some separate program and then import things from there. also, please keep in mind that i am not trying to take a model from a different game, but rather make my own model to put into postal 2.

any help would be appreciated!
