Baked texture looks different than the rendered

Hi,

I'm baking textures to my model. First I create a test-render, before doing the batch bake with the same mental ray settings. For example:

After, whem I'm doing the batch bake with the same settings, the result is very different, than the prerender.
After batch bake:

I did not changed anything in the mental ray settings. What causes this? Please help...

Hmm, there are some contour lines, in the borders of the UV maps (?)

Another example

prerender

batch-bake, baked texture assigned to object

Still no idea, how to prevent this...

If I would like to stay at Maya, is there any possible solution to prevent this?

I must admit you have got me on the lighting but it does ever thing else, try changing the "bake optimization" to multible object................dave

Edit:you can also bake in maya and use the texture in mental ray

Sorry, I do not understand the second comment: use texture in Mental Ray.

Which texture? The baked one? Can you please describe this in more detail?

Thanks.

It looks like you need to increase the "Fill texture seams" in the bake settings so you get total coverage and avoid those gaps between the borders.

Yesterday I tried to make a bake with 256 x 256 resolution, fill texture seams was set to 10, but unfortunately the texture seams did not disappear.

What is the measurement unit in the texture seams terminology? 10 means 10 pixels?

The UV map is correct, there are no overlappings, but these texture seams are very ugly... user added image

Hello,

Ok, now I found the solution...

In my Maya 2012 x64 the 'Fill texture seams' option has no effect. If I set it to 1, or 10, the result is the same. It doesn't matter.

The origin of the problem is, that if I set the 'Bake optimalization' to Multiple objects, then it just ... WORKS!!!

If I set it to Single object, it has no effect.
