Hi everyone!

I've been following this forum for a while! but now i'm here asking you for some advises!!!
I work with a Mac, Maya 2011, topogun (baking)

I have some issues with the baking of a Gear!!! it looks wrong!!! its driving me crazy...PLEASE HEEEEEEELPPPPPP!!!!!

TANKS ALOT!!!

Your UV map could probably be done better with overlapping shells to provide more pixel information to the mesh. Remember overlapping shells need to be offset out of the 0-1 region.

Anyway, from what I can see you haven't smoothed the normals on your low poly there, in maya under the polygon menu's there is one called normals, at the end of that menu is soften edge. If you are getting faceting on the normal bake make sure the high poly has enough divisions to be smooth, If you bake while the object is in smooth preview (pressing 3 on a mesh) then it will ignore the smooth preview, you can convert the mesh to the smooth preview by clicking modify>convert>smooth mesh preview to polygons.

If your not getting flat area's where you want them you can tweak the vertex normals for the low polygons faces to point in the correct direction.

Thanks for the advices the part of tweaking the normal vertex is briliant!

The only part that i don't understand was the UV map, wih an example maybe i could get the right result!!!

Thanx for the answer!!!

Keep in mind that waves on the normal map are expected, it is the difference between the low poly and the high poly, it is how you get smooth surface on the final model.

What is important isn't how the normal map looks by itself but how it looks when applied to the model and is in the engine.

If you think of a normal map like pushing silly putty into a bumpy surface, you will get a copy of the bumps, you can't avoid it and trying to get rid of them will only make the copy look wrong.
