LFX Posted December 9, 2010 Share Posted December 9, 2010 I can iterate over every value in a volumevop SOP, but how can I compare one to another? Or is there a straighter way? I have a workaroundish solution with attribfromvolume SOP: Getting the values from points, which I scattered in the volume. I want to use these values for volumeramp SOP.

Can you use the volumemin() and volumemax() expression functions? 1 Quote Link to comment Share on other sites More sharing options...
LFX Posted December 9, 2010 Author Share Posted December 9, 2010 (edited) Oh man! Yep, Macha refers to the same function. I must have forgotten to check the expressions. Anyway, I wish the documentation of volumes would be more detailed. I had to browse the forums a lot. Thanks a bunch! Edit: Or are volumes the same everywhere - not unique in Houdini?
