How to modify multiple volumes using the same VEX code?


Recommended Posts



If I have multiple volumes like density, color, vel, fuel, etc, how can I write code so that I can copy the volume values from the second input of the Volume Wrangle into the first one. For testing I am feeding the same node into both inputs and simply copy the result but I am still getting incorrect result.


This is what I wrote:


Group: @name=Cd.x

Bind Each Volume to Density: ON

float sample = volumesample(1, @primnum, @P);
@density = sample;

I was expecting the volume to look exactly the same but it looks completely different. I am using Petr's hip file so the volume order is fixed so not sure what's happening this time (before/after):







Thanks :)
