Entity Description

env_spark with directional, glowing medium sized sparks

An entity used to create sparks at its origin.

Note: By default, the sparks jump up a bit from the origin of the entity, so if you are attempting to create a situation like in the picture on the right, you must use the Directional flag and direct the entity downwards.
