Lazy brush entities

Certain brush entities apply its effects based on absolute bounding box (AABB) of its brush model instead of brush model itself.

List of lazy brush entities

• fog_volume
• func_block_charge
• func_nav_blocker
• func_nav_avoidance_obstacle
• script_nav_blocker - not a brush entity but same behaviour
• func_detail_blocker

Internal entities

• func_viscluster

Semi lazy entities

• prop_physics - marks nav areas as OBSTRUCTED based on AABB
• trigger_hurt - marks nav areas as DAMAGING based on AABB
• script_trigger_hurt - marks nav areas as DAMAGING based on AABB
• trigger_hurt_ghost - marks nav areas as DAMAGING based on AABB
• trigger_soundscape - dead players or spectators can touch this trigger which is determined by AABB, while living players use brush model

Example

Example on fog_volume. Green box is AABB and that's the effective area of fog_volume instead of the brush model
