Lighting

Entities

• light — a simple omni-directional light
• light_environment — light from the sky
• light_spot — a stationary spotlight
• light_dynamic — a combination point light and spotlight that can be moved, turned, and adjusted
• env_particlelight — only lights particles (such as those produced by env_smokestack)

Notes

• Naming a light makes it more expensive. Only name lights when you need to. Multiple lights sharing the same name cheaper than lights with seperate names.
• light_dynamic is especially expensive, and will not even show up on some systems
