Vellum Visualization

[mapra]

Hi,

I am trying to access the Vellum visualization attributes so I can use them when rendering. (Stretch Stress, Bend Stress, Stretch Distance, etc.)

Does anybody know how to access them directly?

Thank you!

look inside of Vellum Object DOP/guides node 

and then all the nodes between CONSTRAINTS node and switch12 node, those are responsible to compute the data on your constraint geometry, so you can get them from there and include in your setup

Thank you, that works for me!

@mapra  @anim hello hello, I am trying to do the exact same thing, but can't make it work. Let's say I wanna extract the Stress.
I used an object merge and fed it the stretch_stress wrangle in it. Then I transfer it to my geo, promote it to point and use it in a color sop. It doesnt work.

What am I doing wrong?

EDIT: I figured it out (had to copy paste the entire network and relink some stuff....a bit messy now)
I am gonna try to delete one by one what I don't need

I would love to use the Vellum Stretch Distance Visualization data as a color attribute at render time. I think I need this explained to me in very simple and explicit terms. Any help here would be greatly appreciated. Thanks in advance.

 

SOLVED. Vellum post process output Attributes tab. (face-palm)
