env_flare is a point entity present in the Half-Life 2 series. Creates a red flare. Useful for creating a dark environment with just enough light to navigate. The flickering red light of the flare creates a tense atmosphere and a strong feeling of fight-or-die. Flares are removed from the map once they burn out.

Tip: To make flares like the ones seen in Episode One, create a prop_physics with the model props_junk/flare.mdl. The rest (activation, burning, etc) is handled automatically. Note that this model was only added in Episode One.

Bug: Flares do not spark until one of the three inputs are sent.

Bug: Flares can spark underwater, even though they're supposed to create bubbles. The sparks appear to be the only part of a submerged flare visible from above the surface.
