re0312 36c6f29832 Lighting Should Only hold Vec<Entity> instead of TypeId<Vec<Entity>> (#14073) ... # Objective - After #13894, I noticed the performance of `many_lights `dropped from 120+ to 60+. I reviewed the PR but couldn't identify any mistakes. After profiling, I discovered that `Hashmap::Clone `was very slow when its not empty, causing `extract_light` to increase from 3ms to 8ms. - Lighting only checks visibility for 3D Meshes. We don't need to maintain a TypeIdMap for this, as it not only impacts performance negatively but also reduces ergonomics. ## Solution - use VisibleMeshEntities for lighint visibility checking. ## Performance cargo run --release --example many_lights --features bevy/trace_tracy name="bevy_pbr::light::check_point_light_mesh_visibility"}  system{name="bevy_pbr::render::light::extract_lights"}  ## Migration Guide > now `SpotLightBundle` , `CascadesVisibleEntities `and `CubemapVisibleEntities `use VisibleMeshEntities instead of `VisibleEntities` --------- Co-authored-by: Alice Cecile <alice.i.cecile@gmail.com>		2024-07-14 17:00:54 +00:00
