Hi there, mental ray users !

What mr render settings I have to apply to get rid of texture seams ?
In Maya Software and Maya Hardware render everything is all right .

Another one question - I have 23 warnings in the script editor on the picture.
What’s wrong ?

I’ve figured out that problem with UV seams in MR the matter is that mental ray incorrectly works with normal maps (
But the problem still exists.
With Maya derivatives on I’m getting strange result - some kind of abracadabra look.
So where I can find detailed description of mental ray settings ?
Reference or Manual. Autodesk mental ray help reference is not good for me.

I’ve tried different types of Filters: Quadratic, Mipmap, Gaussian even without filtering at all.
I was reading mental ray Manual http://www.autodesk.com/mentalray-help-2012-enu
but with no result.
Maybe mental ray doesn’t support normal maps in general ?

How were the normal maps generated?  What kind of material setup are you using?

No obvious solution jumps out at me at the moment.  Can you ZIP and upload the scene? That would be the quickest way for us to track down the problem.

I’ve seen the topics on various forums where users have the same problem but
with no solution.

I’m not sure if this will help but I’ve had similar problems in max. The cause of the problem for me was that one or more of the unwraped UV’s were flipped so that the normal map had inverted normals on the affected parts. Doing a -100 scale on them will flip the UV and then recalculate the normal map and that fixed the seam problem for me… but that of corse might not be the case in Maya but it might be worth a shot : )

Can you ZIP and upload your Maya scene with the normal map?  It must be ZIP or else it won’t let you upload.

I already did. But I can not keep my archive in public access on the forum eternally.
And I’ve found the solution for my issue.

Glad you found a solution.  Do you mind sharing it?

For a normal maps baked not quite enough neatly the solution can be
setting up Filter Offset in Attribute Editor equal to 0.5 instead of 1.0
