3ds max 2013 Normal seam
polycounter lvl 12
hello
i have a problem when displaying normal maps in 3ds max 2013
i tried xoliul and 3point shader, both give the problem
i think it is being gamma corrected, i read a few threads and they all said that
but my gamma correction is of
enabling also doesn't help
when i export it in unity, or open it in max 2012, it displays correctly
(edit: on closer look, the seams are still there sometimes in 2012, but barely noticable)
the solution to make it display correct in 3ds max is to remove all the smoothing groups, bake, and display on the model without smoothing groups
but the bad part is that when exported to a game engine it is full of hard lines because there are noo smoothing groups
here is a comparison between max 2012 and 2013
including prefernces
and the normal map (wich has no alpha, tried tga and png)

Using 3dsmax RTT.
I have just been using 2012 as a "fix"
A while ago I also did some tests, and it displays fine everywhere (3dsmax2012, UDK, 3dsmax2013 with the standard nitrous viewport preview, etc)
Only when using Direct3D with Xoliul in 2013(haven't tested 3point since there is no 2013 version yet afaik) there are seams.
If needed I can put up some screenshots of my findings as well.
it's not the bake thats bad, but the preview in max 2013
nitrous only works with the default normal bumpmap in max, not xoliul, but its really ugly compared to xoliul or 3point
Writing a custom shader to return the tangent and bitangent per vertex to the viewport shows flat (or practically flat) colours in 2013, where the exact same shader shows expected results in 2012 and 2011 where the tanent and bitangent vary over the surface.
It's not the assets (or at least that's not the only potential problem) it is the viewport.
And yes I tested this all with nitrous off and gamma correction off, so it should show parity between 2012 and 2013.
booo!
What does it look like if you "render" the scene?
Yep, I've resigned myself to previewing in marmoset exclusively. Why exactly Autodesk would change something AGAIN is beyond me. Seems like a form of sport, really.
