How to make fire

Step 1: Select the entity tool, and place a env_fire where you want the fire to be.

Step 2: Make the properties of the env_fire to what you want.

Step 3: Perhaps add a light, probably flickering.

You have now made a successful fire.

• env_entity_igniter Point entity that ignites a target entity. If the target is an animating model, it will have sprite flames attached to its skeleton. Otherwise the entity will emit particle flame puffs.
• env_fire Point entity that handles a single flame at its origin. The flame causes heat 'damage' to other env_fire entities around it, and will eventually ignite non-flaming env_fire entities nearby, causing the fire to spread.
• env_firesensor detects changes in heat nearby. Parameters: fireradius, heatlevel, heattime. Outputs: OnHeatLevelStart, OnHeatLevelEnd.
• env_firesource Point entity that provides heat to all nearby env_fire entities. Cannot be extinguished.

Smoke & FX

• env_smokestack Point entity emits a constant stream of smoke. Place up to two env_particlelights nearby to add ambient light to only the Smokestack's particles.
• func_dustcloud Brush entity emits a translucent dust cloud within its volume. Use the trigger tool texture.
• func_dustmotes Brush entity emits sparkling dust motes within its volume.
• func_smokevolume Brush entity emits smoke particles within its volume. Use the trigger or fog tool texture.
• env_steam Point entity emits a jet of steam.
• env_spark Point entity emits sparks from its origin.
• env_embers Brush entity volume in which to spawn fire embers.
