really weird normal map artifact...

fritz

hey guys. i'm getting really close here. i did a test normal map on this guy. normals came out fine for a test...no seams YAY!!! however, i get this weird artifact when i render. it's rendering the portions of the model i brought in peice by peice from zbrush to bake the nomals....really weird. anybody have this happen before?

check your green channel, or rather all of them, make sure you dont have some inverted sections of your normals

might also have some random piece of geo still in the scene perhaps, but hidden? if so try removing it... it shouldnt affect it, but when bug fixing you remove all possibities you can, just in case.

nevermind...i'm dumb. i had an alpha in my diffuse.

heheh. we all make these little mistakes from time to time
nice looking model though! can't wait to see it finished.

MOP...thanks so much. i'm tryin man. next i want to try and bake in some spec and then paint the spec up the way pior did in his tut. i put a lot of work in figuring out how to minimize seams on this guy....which is really exciting once figured out. hopefully i'll update soon.

r13: thanks so much for the tips...thankfully it wasn't something so technical...hahahaha.

Ha yeah well it's true that it helps... Just be careful with it : it will give you a nice base to help placing correct highlights, but if you use that straight as a spec it's going to give you a 'locked' highlight which can be annoying.
