I’m developing a VR game. There are two identical simple levels with a 15x15 landscape, a small lake (built-in Water plugin) and a HDRI image sky. When I open the game, the first level works fine. But if I open the second level via OpenLevel (by Obj Ref) node, the game lags for about 30 seconds, then everything is normal. FPS does not drop and stats do not change, the image just twitches ~30 sec when I turn head. If I open the second level directly from editor then everything is also fine. This happens only when I load level via OpenLevel (by Obj Ref). Also without Water in level everything is normal. How can this be fixed?
