Normal Mapping

Gannon

I'm trying to transfer Maps in Maya from my "High" mesh to my "low" mesh. Problem is i'm getting really crap-tastic maps.... Does the low mesh have to envelope the high? the only different is ones got spheres in place as bolts that are combined with the mesh to give it that look..... it's driving me nuts I've been fooling with this all day....

Ok so I've got the maps working but the detail just isn't popping out strong enough, Suggestions on how to fix it?

Also check out this. By the way, make sure your high-poly is a subdivision model.

it kinda looks like you need to increase the "Search Envelope" in the Transfer Maps menu. Right now it's set to 0% and probably need to be increased higher. You can also change the "Display" to Cage to see the actual envelope cage

Theres no difference from your high and low besides the screws/bolts. Without that difference the normal maps going to be a flat blue for the most part.

what mookster says.. using the same model will get you blue, using almost the same model will get you little bits here and there like you have. try checking out more examples of 'high poly versus ingame model' pics (dom war or unearthly challenge) and see the difference

This science, is why your maps are coming out bad.
