Problem: Actors briefly walk in air

Hi, i was wondering if someone else knows what is causing actors to briefly walk in the air? Does not always happen. Almost seems like the engine is not updating gravity for some actors.

Any input is welcome, thanks.

You have to provide more details eg revealing the BP which drives the dinosaurs around…
Or probably the landscape’s physics collision is not as fine as the actual landscape… which describes the discrepancy you see above…

Update: Still happening, sometimes everything is fine, and then actors walk again in the air.

It affects all actors, There is a Master Blueprint, and it affects landscape randomly, sometimes it is fine, sometimes not. Sometimes for extended duration no walking in air.

Okay i think this is a bug. When you have the landscape selected, then start preview in editor window, the walking in air takes place from time to time.
