Hey there! I'm following an older Houdini tutorial and the guy is using a VOP SOP. Since I'm using Houdini 18 I just went and used a Point VOP. But now in the next step in the video he is editing the "Geometry File" parameter. When I try to do the same, I'm finding that parameter greyed-out and inaccessible (see attached images). Any help would be much appreciated so I can continue learning. Thanks in advance!
Hi I am trying to do this old POP tutorial, there is a section where he takes the red color value and modulates it with a spline ramp. (around the 4 mins mark) For some reason I cant recreate this at all. He is using a VOP sop and I am recreating it in an attribute vop , i think that should work fine . when i connect my ramp it just removes all the color. Thanks https://vimeo.com/95644892
shadowst17 posted a topic in General Houdini QuestionsHello, I want to create an attribute that over time decreases on each point depending on when they entered the event. Pretty much an age attribute. I can't seem to figure out how to get it to work as you can't seem to reference time within an Attribute VOP and any tutorials that have something similar utilise temperature or particle age which only work if using those types of FX. Any help with this would be great as feel it can't be too difficult and would be incredibly useful in a number of my projects.
