This is a fantastic add-on for Blender... but my understanding is that it enhances the existing Blender Elbeem fluid system, not replaces it.
I guess I'm saying that for us to get an addon like this, we would have to have an actual native fluid simulation system in Lightwave to start with.
Regarding houdini... Alembic is your friend there.. just export the particles as alembic and use odtools alembic to pfx. I still might make up something like this script for houdini though, as it has its advantages in certain cases and doesnt inhabit the limitations of the pfx format.
Yes, given LW's Alembic vertex count limitations, and pfx format limitations, having a way to import Houdini fluids/bubbles/foam as object sequences would definitely be useful.
Is there an equivalent solution for moving fluids between Houdini Indie and LW using OD tools?
