Ratman Posted January 27, 2010 Share Posted January 27, 2010 Hey gang, I'm looking for a way to basically "lock" an attribute onto a point. Say I have a point cloud with an "off" attribute that's 0, I want pass a box inside it and have the points that pass inside the box to get the 'on' attribute of 1 and have it stick, much like an attribute transfer, except once the box activator passes the point I want it to actually stick on the points so they stay activated. I was able to get a working solution bringing in my points into CHOPs and using a Trigger chop and just extending the attribute, this so far "works", but the problem is that any slight change and it re-evaluates the network and it tends to be annoying, unless I lock it while I do other things in my network. So i'm wondering if anyone has a more elegant solution, at this point I'm looking into vex/vop world for a solution. Quote Link to comment Share on other sites More sharing options...
pclaes Posted January 27, 2010 Share Posted January 27, 2010 Sop solver! You require the points to have "a history" very much like pops. The sopsolver will give you access to the previous frame. Even though this is a bit of a different type of effect, it will trigger the points as well (in vops if I remember correctly) - the file is called particle_fight: Quote Link to comment Share on other sites More sharing options...
