the regular forces and relaxes have a shine to them, it's not one flat color all the way around it, which is why textures set to those colors look flat and not the same.
In lamens terms, textures can't replicate exactly the colors of a coded joint, however they do a pretty damn good job.
*dl and lp pal if you want an example, he is using the knox color for his joint textures*
It works best with pure joints. Other colors give it another color shade...it could work pretty good with qs joints...but pure is perfect.
U can work with the colors to match the normal textures...
But as advice i'd say don't waste money or 128...buy 512, same with normal textures
