So here’s my standalone game, and as you can see there are not that much complex or highpoly objects. When I start it in Blender there is lagging when I spawn my player. How to stop it, and tell me if it’s lagging to you.
Ok… I can only see that little bears? move slowly but the camera rotates quick and flow and when i have added all turrets all work fine.
But it is imposible make a better valoration without see the blend… or if you dont want to share it, a video showing the issues you are talking about would be great.
Ok I’m going to send you my .blend, but I trust you, respect that.
Try to dissolve some vertices that are flat. Like on platforms and flat surfaces and that should do the trick
