I didn't do the model. I just did the textures to get some practice and to do something new. This is my first attempt at skinning a weapon, painting metal, and using bump and spec maps. Thought I'd post it here and get some crits on it. No lights, 100% self-illumination 1 spot 2 omnis, 0% illumination (I'm very noobish…
You have to think of the spec map differently than the diffuse. Right now, it looks like it's just an adjusted greyscale version of the color map. The spec map is used to determine the brightness of the specular highlight if there happens to be one. So you wouldn't want to have painted in highlights like on the barrel…
Played around with the textures a bit more. Took a lot of the highlights out of the diffuse, messed with the bump and spec maps a lot, put the spec map in the correct place, hehe. Had it in the wrong slot for the original pics so it wasn't doing much of anything in those. :P I updated all the jpg's of all the maps so you…
What engine is it intended for? The way the spec maps are handled depends largely on that. When doing them for Doom 3, for instance, it's different from the way it's normally done for regular pre-rendered hi-poly stuff. The shape of the highlights can be painted into the spec maps to simulate the effect of the light…
