Hello everyone,

I was wandering how would I need to approach the need to trasnfer an attribute, say N, from a geometry to and identical one with an effector or some sort of object which position determines where the attribute is transfered.

When the transfer is from an A to a B object, the solution is a pretty straight farward classic Attribute Transfer Sop, but how about the A to B through C scenario?

I have found an easy fix with Sops: boolean substract a sphere form a grid A, copy the normal attribute from grid A to the product of the boolean then attribute trasfer from the product of the boolean to the B grid. Still this is very intricate and culd easily get superslow when dealing with more complex geomety, how could it be build inside Vops using some sort of geometry as bias/effector?

I attached an Hip with what i have so far

Thank you for yor time

Hello,
why not using groups with attrib copy?

Hey,
sounds like you could do this in a couple different ways.
If I understand right, you could approach it like this.

Build your own attrib transfer either in VEX or VOPs.
Just using pcopen / pcfilter approach.
Make your mask object a fog volume.
In your custom attrib transfer you can import the mask with volumsample.
Then multiply attrib transfer result by the volume value.

Just brainstormed away from my PC…
If you need more detailed help let me know.
