reelinspirations Posted March 6, 2023 Share Posted March 6, 2023 Hi, I have a vellum grain sim where I set a value based on POP Attribute from Volume based on a volume I created. This works great and is returning an expected value. What I'm trying to do is access the MAX value of that attribute at SOP level where I'm 'feeding' the vellum grain sim. I'm wanting to delete the grains BEFORE they enter the sim based on how far the current grains are inside my volume. So my sim starts normal, then as grains enter the volume, I start reducing how many grains are sent into the simulation. Any ideas on how to do this properly? Thanks!

ryew Posted March 7, 2023 Share Posted March 7, 2023 (edited) I don't have time to check out your scene, but one shortcut I've used in the past is with an AttributePromote SOP set to "maximum" and promote it to a higher geometry type like a primitive or detail type to force it to just take that max value, and then promote it back down to a point attribute with another AttributePromote SOP so that attribute is overridden as just the Maximum value for referencing.

paranoidx Posted March 7, 2023 Share Posted March 7, 2023 In Sop Solver promote that attribute to point, then in DOP import you transfer that attribute out Quote Link to comment Share on other sites More sharing options...
