Get vector data from map over deformed mesh

Recommended Posts


So I baked out some kind of vector flow map on the character. The idea was to use it back in sops over deformed character.

Ofcourse the bake is done in a single frame. So when those vectors are applied to a deformed mesh, they are constant to the world space, which completely make sense, but is useless for me.

Since this is a vector map and its stored as a color map, there is some kind of "gradient" on the deformed mesh that could be computed as a change of the flow map? Do I make sense?

For example you have a character where the flow always go from the shoulder to the hand. And once the character gets deformed (animated) I want the flow (vector) to always follow the rule "from the shoulder to the hand".

And yeah my flow is a vector, not a float. And I need those vectors in sops.

Dont know if I explained this good enough. Any1 any tips?

you can use Attribute Reorient SOP to reorient the vector attribute from rest geo to deforming one

OMG THANK YOU, thank you, thank you!!!

I didnt know this would be so straightforward
