Cuenk89 Posted March 28, 2016 Share Posted March 28, 2016 Hi all!I have a problem with point normal.In my scene I have a voronoi fractured object represented with one point per fracture. I simulate these points with POP sim, but I can't give a normal direction that follows an (alembic) animation (It's difficult to explain)I attatch two screenshots and the basic scene.Thanks in advance!

kungFu Posted March 30, 2016 Share Posted March 30, 2016 Hi Cuenk89, I'm not completely familiar with the old POP, but it looks like your particles are not inheriting velocity from your geometry (so no rotation). Normally a trail SOP will compute the vel you need, but I believe this has to be done before you polysoup the chain. I've attached your file with a small side chain attached that shows the workflow with the newer pop with adding a the trail sop and setting the particle to inherit velocity from souce inside the POP SOP.Test_particle_js.hip -js 1 Quote Link to comment Share on other sites More sharing options...
Cuenk89 Posted April 1, 2016 Author Share Posted April 1, 2016 Thanks kungFu for your reply, but this isn't what I want. It seems that attribwrangle deletes the normal attribute. I made a new file pretending to give an average normal to each piece using foreach subnetwork. It needs to refine some parameters...
