Hi there,

I'd like to combine 2 vdbs (one eroded, the other dilated) through a 3D noise map acting as alpha mask.
Do you know what could be a suitable workflow?

Thanks for any help!

Assuming you have level sets, try linear interpolation with a volume wrangle? (see attached)

the only trick is that volume wrangle only iterates over set voxels, so you may need to resize your narrow band to activate a wider topology (to account for the data in the second input).

Hello and thanks for the helpful tip, jbudsberg!
(and for taking some time to produce the screenshot)

I've never used volumeVop and volumeWrangle. Nice to learn something new (-:

cheers
