Attributes in Volumevop


Recommended Posts

Hi, 

Im using colour as an attributes to change parameters of a noise inside a volumevop. I can use the 3 RGB values to give different effects to the noise but i would like to use another colour map with its 3 values to change the same noise. 
The problem really comes down to how I can create new attributes from Cd and get more colours to work with. I have used Bind and Bind export and the Cd variable but I cant get it to work with a new attribute using create attribute.
Im new to Houdini so any tips would be helpful.
Thank you
