SoftImage XSI 6.5 - Problem Using Ultimapper to bake Normal Map.

Ephesians 2:8-9

When i Bake normal maps through Ultimapper, all i get in the texture is black. It happens when i try to bake any map weather it be AO or Normal Map. I've tested this on a cube and have gotten the same results. My low rez mesh has tangents and ultimapper applied.


Any idea why this would happen?

Might sound stupid, but have you set your UV Maps?

Might have better luck over at xsibase.

Do you have a texture projection applied?

If so:

Do you have more than one texture projection applied?

If so:

Do you have the right texture projection selected when baking?

If this doesn't help, you may want to post some screenshots.

All as you said are current and look fine. There are not additional projections. Just the one. I initialy used "Unique UV's" for the low poly "game" model. THe high rez has no tangents and no UVs. I did however try a test by creating a new scene, created a box, UV'd the box with Box mapping, then duplicated the box and teccilated it. Then applied ultimapper and repeated the process to bake and I still got a black texture. I'm leaning towards a wrong setting but i am not sure.

Did you press "Compute" in the Ultimapper window before generating?

That did not seem to work.

I also tried opening old 6.01 scene files that baked successfully in XSI 6.01. However after opening in 6.5 and trying to rebake, the black texture seems to occur. I must be missing something in 6.5. Its weird.

use xnormal!

did u select the highpoly ?
if its more than one object, you need to create a group with all parts, and select the group..
i think it would be easier if u posted a screenshot or something, wer all fumblin in the dark here

Ephesians 2:8-9

yup did all that. What baffles me is that this happens in a simple scene of creating a box in a new scene. Fresh scene gives me the same results. I'm now thinking its one of 2 things.

1. It's a bug in 6.5 that was overlooked.

or

2. there is still a setting or process i am missing.

This never happens on 6.01 though. It's consistent throughout any scene i open weather it be old or new. I just dunno.

here, i created a simple sample project with a working ultimapper setup, hope that helps.

I think I recall something about not letting UVs overlap when you bake, if you got overlapping, remove it, move it outside the box and bake it and then just undo or move them back. But not sure.
