Thank you for your reply. I guess there’s no choice but to output in high-poly when detail is needed.
I’ve heard that UE4 has tessellation and it could be applied to the imported Alembic. I fully understand the reason for removing tessellation in UE5, and most of the technologies can be substituted with new features, but it seems impossible for Alembic. This is a critical issue in cinematics.
I’m considering trying methods such as geometry scripting, but it’s a big problem that so much time is being spent on a problem that could be solved by tessellation alone.
I’m seriously considering whether to use UE4. It’s such a ridiculous worry.
