Hello to whoever is reading this post.

I have ran into an issue.

Whenever I want to import groom cache (alembic file) from Houdini hair gen node to Unreal 5 I only get the first frame, static mesh and no groom cache, but if I cache it out from the guide groom node, everything suddenly is alright, Unreal 5 reads it fine and imports the groom cache (strand cache).

I don't use skin for this groom simulation in Houdini, since it's a vellum simulation out of lines (you can see it in the screenshot I attached), I use this simulation as my guides in guide groom and then I use the guide groom for my hair generation in hair gen node?

Am I missing something?
