Hello,
Just wondering, is it possible to use the new remesh sop on dynamic geometry (points popping in into existence and etc.) so that it doesn't build new topology each frame? Thanks.

I don't think that the Remesh SOP could work like that with its current input.

In order to avoid changing topology, you'd need to somehow create a rest topology, and try on every frame to map that topology onto the new surface, which sounds like an ill-defined problem. People who've been at it for longer than me might have a better solution for your specific case, if you can provide an example file, but in the general case, it'd be nearly impossible.

Hopefully an example would help open up some possibilities.
