Can you help me please with one direction? I don't understand what I'm doing wrong and I can't sleep at night because of this. I can't find a solution.
I succeed only with Sprites 2D, but i need Vertex Animation from Particles directly. I try also Alembic and mesh and is very heavy to load becouse i have big amount of particles.

I try with this: https://www.youtube.com/watch?v=zHaCIVkqrFU&t=325s [www.youtube.com]

How to import Alembic fluid into Unity

Yis not geometry.
Is just particles.
no meshes.
Becouse the mesh is very heavy.... a lot of particles.
And is load very slow in Unity.
Just particle sequence.
as alembic or....bgeo.sc. or
I try with Alembic and maybe is solution but i dont know to keep the colors from Houdini.

Enjoy this time of Year.

Tanks.
