How to make actor physics replication work with medium ping

[anonymous_user_8f6e4946]

is correct. Your problem is the physics simulation portion. To accurately play back corrections, you need to store the physics state of the entire physics scene each frame, warp to that point in time, apply all the corrections you have for that frame, and then continue forward.

Ideally you’d do that by storing playing input or forces for each cube, etc.

The NetherRealms guys did a good talk on what this takes:https://youtube.com/watch?v=7jb0FOcImdg

Basically, from what I have gathered, I should give up on even trying to get a simple box to simulate on the client and the server. I can’t believe Unreal doesn’t support this. Surely there is a solution without determinism
