hi,

at SOP level im modifying my volume density with volume vop.
i would also need to output a custom vector attribute(volumetric data) from volume vop that i could use in my volume shader.
how do i add new attribute on top of the regular density in volume vop?

cheers,
Kustaa

you can branch from source volume 4 times
append name SOP after each branch
name first density
second for example vel.x
third vel.y
fourth vel.z
merge all together
then add your volume VOP
and you'll have vector attribute named "vel" which can be modified

thanks Thomas!
exactly what i need.
i noticed that i can also create two volume primitives, one with scalar and one with vector and then merge them.
