I feel like I'm missing something. I have a sim with animated geometry emitting particles which looks fine up until I try to use the geo as a collision object. When I add the collider, the particles get blasted away from the surface even if I completely turn off the velocity from the collision object. Any ideas where to look to figure this out?

Your file seems to be missing the assets so I don't see anything when I load it into Houdini. So, I can't say exactly why your file isn't exporting correctly, and can't speak for the alembic file to tell you why it's not working right.

But, for FBX files, you need a static polygon/vertex count for them to work properly. Which is fine for something like character animation or an RBD sim. However if you try to export something like a fluid sim or a plant growing, where the poly count is changing all the time, it won't work. You may get a few frames, but then it will break.

Can you supply your file with how you have your network actually set up? or share the HDA asset file so we can get your scene working?

Now I feel silly. It was pinned. Thanks!
