volume attributes

[kustaa]

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.

cheers
