my bumpmap is not showing up.. its liked to the right UV just like the color textue map.. but on the bump channel.. so that should be right.. is there something in the render globals or atributes that would prevent it from rendering ??

also is there a way to see the bump map with the hardware texture on ??

ambient lights do not show bump maps... You may also need to UV map your model. Those are the only 2 reasons I could think of.

ambient lights cast light everywhere. They don't really break for shadows, although they do cast slight shadows. So, bumps don't really get calculated with them. Hope that kinda makes sense.

Hi Pony,

https://www.aliaswavefront.com/en/Com...ent/index.html

An ambient light in reality is just a brightness wash applied over the render, and normally destroy a good looking render if used incorrectly. Maya´s ambient light does differ from the pack since it does compute the position of the light, however not as much as you would perhaps like.
That´s why the bumpmap isn´t computed within the ambient light.
Go through Mike´s three point tutorial to get a good sense of lighting a 3d scene. That way you´ll preserve the bump map, and achieve a fairly better render.

Well a update for you all. in V4 of maya. You can not have a bump map on more than one UV set. This was suposto be fixed in 4.5 but not compleatly.

Basicly you cant use bump maps with multiple UV sets. It will only bump certain UVsets that are on the same shell, >> eraticly.

Maybe it is fixed better in V5 ..
