Hello,
I'm having a weird problem where polygons in my alembic scene break apart.
What I'm trying to do is to import an alembic scene, select a few polygons from that Alembic scene and emit smoke from them. Like an engine emitting smoke. But when I have selected the polygons I want, they break apart during the simulation.
The steps I've done.
1. Importing the alembic scene into a geo node, made it a bit smaller and put a null node in the end.
2. Created a new geo node. In this node, I have an ObjectMerge (imported my alembic file again), then a convert node (to make the alembic scene into polygons), then a blast node (to only select the part I want to emit smoke from).
But here comes the problem. When I play the animation, my polygons from the blast node breaks apart (I've included a screenshot for this).
I have missed something but not sure what.
Would be very grateful for any help.
