JDee Posted March 10, 2017 Share Posted March 10, 2017 (edited) Hi Can you guys give me an idea of cheap way to reproduce a fading trails inside a volumes ? Can't find anything useful in simple trail sop like numbers of copies or something to work with in vop. I understand it's simply multiplying function or dividing number of copies by number of each , but can't get anything working at this moment.

trzanko Posted March 10, 2017 Share Posted March 10, 2017 Create an id attrib on points, trail the points, run a for each over each id and you can get a u attrib by @density = chramp("fade",fit(@ptnum,0,npoints(0),0,1));, then create a fluid source and create a density volume by stamping points. You could also use just points and stamp the points and then use the motion blur tab in the fluid source but the first method I mentioned gives you more control. Hope this helps, -Tighe Quote Link to comment Share on other sites More sharing options...
