UE4-Vertex animation tool or Alembic import?

melviso

So I am trying out importing cloth simulated in Blender into ue4. Would using alembic file format to import the simulation affect performance? or vertex animation tool would be more ideal. From what I have researched, vertex animation tool is limited to 8192 vertices so geometry higher than this won't work.

Alembic uses a lot of memory when the mesh has a lot of verts, or the animation is long. The more verts it has or the longer the animation is, the more memory it will use. So for game application, it isn't always ideal. But for what you would use it - pre rendered animation presumably, its fine. In 4.20 they added streaming for alembic, so that should help, but I haven't tested it so I can't say that it works as expected.

Ok. Thanks mate :- )
