In-progress join and interactable foliage replication

[LordStuff]

Hey there! Long time I left this topic lying about, but it came up once again (dunno what else to do with my free time lol).

Have you taken a look at it? Maybe found a solution?
Tried to do this with RepNotifies instead, it produces good results with low instance counts but with higher instance counts it even produces Engine crashes

I guess we can’t avoid splitting up high instance counts into partial updates which would ultimately require us to also somehow avoid desyncs while the transmission is in progress.

I would be hella interested in talking to some Unreal dev about this topic, take ‘Grounded’ for example, they have thousands of grass blades you can chop down. They have to be foliage too. And with instance counts above about 1000, syncing it becomes a problem… Interesting topic however

No, I didn’t look into this since I won’t have in progress joins. But I guess I would send it piece wise to the client during the clients load, then when everything has been send over I would add those instances on the client. As for avoiding desync during this process, I would block any change to the HISMCs and either queue those changes till the client finished, or do a delay loop until the client finished. Also I would delay loop the change from any foliage actor that should get removed and added to a HISMCs.
