I've selected my character that has animation in it in my level sequencer. Once I play it, the hair is there by itself and isn't attached to the mesh. How can I make sure the hair/fur is attached?
I need more information. How are you attaching the hair to the character? Are you using Ground Strands or generating the hair directly on the character? How are you generating the hair exactly?
Have in mind that only sketal meshes are supported. Meshes with alembic animation baked in are not supported yet.
That means that in UE the fbx file was loaded as a merged single object but each object component have a unique ID. In Ornatrix, Guides from Mesh, specify which object IDs the hair will be growing from.
