mirrored UVs in maya for normal maps?!?!?!

slosh

ok, i have 2 problems. one, i have a bunch of mirrored UV pieces and the normal maps dont show up right in maya. is there some good way to fix this? i have heard of makin a copy of ur normal map, flipping the green channel, and using that on the mirrored pieces but this is pretty hacky. is there a better way? also, is there a way to do it without getting the crazy seam between the mirrored pieces? i need some help with this bigtime!! thanks in advance!!!

which version of maya? 8.5 can handle mirrored pieces fine

you need to check the use maya derivatives box in the rendering tab.. dont have maya handy so can't give directions but if you google that should be able to find it

rooster: any update on that "maya derivatives box"? i cant seem to find it...

Did you actually get this to work?

I'm finding that Maya Derivatives just renders it wrong differently. Still not properly.

render settings as seen in some tutorial as well.

I'd like to avoid silly duplicated shading networks with flipped green channels etc.
