Switch certain dynamic occlusion entities to static occludees when we know they can't move - convar `dynamic_occlusion_pausing` (0 = off, 1 = codelocks + industrial adapters on boxes, 2 = codelocks on doors) - currently (and by default) every entity is considered dynamic if parented - now certain entities can indicate if they are static (like boxes) - converts codelocks to dynamic while the door is opening, converts back to static once finished - will check all parents so a box parented to a tugboat will still be considered dynamic since it will find the tugboat as root parent - reduces dynamic ocludee count by 80% (417->74) on a sample base (converts nearly all codelocks and industrial adapters) - refresh entity dynamic status when running `refresh_renderers`
