@deepfriedwalrus1 It's a little complicated. First you have to get the files out of the game using some special tool for it then you have to find a blender script floating around the place to import them. After that you just need to follow a guide on how to get blender things into the source engine and screw with the textures until they look right. I will warn you however that anything that isn't a named character or a regiment of renown will not have any colors assigned to them so a lot of the empire models will just be white where other colors are supposed to be. I do not think there is a way to make it automatically colorable so you'd have to do a lot of work editing the texture itself.
@BaronR I want them too but sadly like I said I've had problems porting them over and am probably doing to stick with the first game for now.
@makar55 I haven't exactly had the best of luck with porting from the second game, sorry.
@JawSFM For me that option is under the menu when you right click an empty area on the menu but thank you for letting me know about it.
Anything specific Orcs in mind? I got some other stuff planned already but I can see what I can do. No promises though since some of this stuff is a bit difficult to work with.
