and it's pretty darn accurate

i used an AR2 vxl, which is regular blocked shaped thing
here's
what i painted and assumed to be perfect:

what the autonormaliser did:

u can see that it's pretty close, and should look similar ingame
(here's a recent screen of AR2 with my manual painted vxl there)

and the great thing about it, it doesn't hollow out the vxl :D:D
