Description:
2DDL PRO is a tool that craft procedurally a Light system for 2D Environment. 2DDL works like a real Light in 2 dimensions.The Mesh Renderer is constructed taking into account the obstacles(Casters) in the scene.
Because is a Mesh, you can pick any shader from this package o built your own.
2DDL is totally dynamic, this mean that you can re-arrange lights and obstacles, and the final result is affected in real-time; or you can choose a Pre-Baked Light and thus avoid the calculation in each frame.

NO CODE required.
If you're starting using Unity, pick up from menu and 2DDL will start working immediately. If you are a Pro Developer, it can be so flexible as you want.
