Problem with normal points as voronoi fracture parts


Recommended Posts

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!

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
