What modern cool texture baker could bake from UDIM textured hi-res?

gnoop

I mean beside Mari, Modo, Max/Maya with Arnold.  Is there a way to do it easy and simple?   In Substance , marmoset toolbag or something?

Substance Designer have support for UDIM in its baker

It could bake to target model with UDIM unwrap for sure but I am asking about baking from UDIM  model , a hi -res one.

As i mentioned in the other thread use Mudbox. 

gnoop

Thanks oglu,   I wasted my trial for nothing a while ago  so couldn't check it now.   It does bake using UDIM unwrapped model as hi-res one ?  Could bake UDIM displacement  on hi-res   into normal map of  a game model ?

Eric Chadwick

Max does this too, since you don't have Mud anymore. 

gnoop

Yeah,  I know but is so painful there.  It really support UDIMs only with Arnold texture node and baking with Arnold is still so much a puzzle.  It needs low res to be never intersecting hi res surface

Eric Chadwick

Oh weird, is the intersection thing an Arnold bug? Doesn't happen with V-Ray nor scanline.

Max also has the multi-tile map that supports udims that isn't an Arnold map.

I tied it couple times but it never worked with UDIMs. Does it really?   I once managed to get it working with some other naming convention  but couldn't recollect now what it was?    And I had other issues with Max RTT  as usual;  super slow , weird artifacts everywhere, etc so haven't tried to bake something in MAx for couple years already.   Is it better now in 2020?

As of Arnold baking  from what I tried last time it could bake only complete map with a special world normals material  for example  and since the ray tracing occurs starting  only from the surface of low poly object itself   so whenever  low poly goes beneath  hi-poly   it makes a hole.    Am I missing something?  Haven't updated it for a while.

With Arnold I don't know how to do a material that would do Height map.   It should be ray distance or something  in between hi res surface and low res surface? Do somebody have an idea?    I bet it should be possible somehow.

I'd guess designer could do it with the transfer texture Baker.  I've not tried though

Does it read "UDIM" token in texture path for "transfer texture" or something?    I tried it  a while ago and  seemed it hadn't
