In UE5 Preview 1, I have an issue where large HISM static meshes are disappearing unless they are Nanite. I’m using the Add Instance node to create HISM spheres that are scaled at 140000000.0 on the X, Y, and Z, using the engine’s default sphere that is 100 cm in diameter.
This doesn’t seem to happen with very small spheres, which I can’t use for stars in a space game. The large spheres worked just fine in UE5 Early Access 2 at the same 140000000.0 scale. Could this be due to the optimization features that were implemented in UE P1?
