So... I set up type 3 but the raiders don't match up. If I have just the type 3 it looks like the 'dirt' on them is stretched by the mesh and the head doesn't really match the body. I tried a type_3_raiders mesh but they're too clean and the head skin colour still doesn't match the body. There's a dusty raiders mod out there that comes closer but still doesn't line up (for some reason the jackal girls have an almost greenish tint to them).

Is there one raider type mod to rule them all? Do I need to post screen shots to clarify?

You need to find a Type 3 compatible Raider skin texture.

Here, you can use this:
