[edit] Description

This shader is for the Projector component and will let you have an additive effect projected onto objects as opposed to the built in multiply effect.

[edit] Usage

Place this shader somewhere in your Assets folder hierarchy. Then, use it on a Projector component's material similar to how the blob shadow in the Standard Assets is set up.
