i’m interested in learning how to do normal mapping for games. i’ve got a subsurf model and a tri based model and i’m attempting to get the tri based model to follow the shape of the subsurf model quite closely.
here’s what i’ve got so far (the eyes aren’t done yet)
i’ve kind of made the tri mesh (black) pass in and out of the sub mesh (red) so that it has as similar a shape as possible. i figured this would make things easier for the normal mapping process and it would also mean that if the normal mapping was switched off the tri map would still be a fairly close match.
am i going about this the right way?
