Alembic bad sampling rendering

hi guys~!

I import Alembic of clo 3d in UE5

The movie is set to 24 fps, and there is no problem in the scene preview

However, in the movie rendering queue, if the anti aliasing temporary sample count is greater than 1.

The rendering will show the help.

How to solve this problem.

thank you~!
