chunkified Posted November 16, 2008 Share Posted November 16, 2008 (edited) Hey all! I've got a fracturing ground animation and i'd like to emit some debris from a certain area. I grouped the area i want to emit from at SOP level and am using this as a Source Group. More points are added to this group over time. Basically i only want one particle to emit per point in the source group and can't currently do so?!?! Any thoughts on how to achieve this? Thanks Edited November 16, 2008 by chunkified Quote Link to comment Share on other sites More sharing options...
Rudinie Posted November 17, 2008 Share Posted November 17, 2008 Check out the expression "haspoint", you can use that to check if a point is in the group on sop-level. Quote Link to comment Share on other sites More sharing options...
anakin78z Posted November 17, 2008 Share Posted November 17, 2008 (edited) The easiest thing is usually to delete everything else from your source geometry, then use $NPT in the source pop as Impulse Birth Rate. Make sure Constant Activation is set to 0. That way you'll only birth as many particles as you have points in your source. -z Edited November 17, 2008 by anakin78z Quote Link to comment Share on other sites More sharing options...
