How can I get the density to falloff on a particular axis of the interior ocean with Karma Volume Shader?


Recommended Posts

Hello!

I need to shape the density (falloff on particular axis) on the ocean interior geometry. 

The Karma Volume (default) density is constant throughout the ocean interior obj. I tried converting the obj into a vdb to create a density attribute.

Then I tried getting bbox min & max values manually using geopropvalue bboxmin, bboxmax & P > subtract > divide to get values and multiplied by the density.

This doesn't seem to work as I get a half/half look most likely do to improper mapping... 

Could someone please rectify this and make it work? :)  Thanks!
