Hi everyone,

I guess this subject has been trat many times but i don't have the time to check, deep apologies.

I really need help, I made a fire and smoke simulation and i want to export it as an alembic file to import it into Unreal Engine 4.
I got a file cache for my end result, I put it in a nul, checked all attribute come into the nul, then I connect the rop_Alembic Node.

I clic on Render, but my .abc is only a 2kB file and unusable into unreal engine. Why ???????

need help plzz asap.

Thx for your answers.

Alembic does not support volume grids, unless I'm mistaken. Is unreal engine expecting to import volumes using alembic? I can't imagine a game engine importing a volume in the first place. They normally use atlas textures and cards for smoke and such. Maybe someone that know more about Unreal can chime in.
