Scan in suits? Not sure what you mean.
I just try to get as much reference pictures as possible in high resolution, gather all the logos needed, draw the design and restart the LFS like million times to get the logos placement and lines linked together properly.
BMW suit still has some bugs, but i just don't have nor the will nor the knowledge how to fix them, because it seems that left and right arm aren't perfectly symmetrical.
I just hope they will add the suit cmx to the cmx viewer soon, that would make the suit skinning easier.
