Light Layer 3D effect

Added an effect to play with. It automatically calculates a normal map for a layer and then provides, a single diffuse, ambient, and specular light on that layer. Works best for 3D objects and shapes.

The light generally must be coming from the camera direction into the screen, but you can play with the depth of the light specular to see different effects.

There is also a light diameter control to make the light more focused.

An example project is included to show how parameters are generally set.

Normal step controls how dramatically different the generated normal map will be, you can use Normal debug to see what the normal map looks like.

@Moonbit - I hope this one is useful for you in your Hopp game :) - please let me know any feedback.
