midicon Posted September 26, 2015 Share Posted September 26, 2015 I need help with this effect. I'm trying to get particles to emit and follow along the surface. I have a piece of geo. and a emitter with a POP VOP that should be creating the creep along the surface part. but it seems that the particles are sticking to one edge of the mesh. I'm sure its an easy fix. prolly a world space issue but I can't lock it down. I have attached the geo and the scene that might help with the explanation. any help is much appreciated. Thanks Rob CreepTest_02.rar Quote Link to comment Share on other sites More sharing options...
Atom Posted September 29, 2015 Share Posted September 29, 2015 (edited) Hmm..still trying to understand your setup. You are taking the particle life and dividing it by the age and using that for the U coordinate of the UVs. Then you are taking the particle number as a seed for a random number which becomes the V coordinate. This UV then gets routed to the position leaving the Z value set to 0.0. So all the particles are always going to sit on the Z groundplane right? Edited September 29, 2015 by Atom Quote Link to comment Share on other sites More sharing options...
