SpriteOccluder2D

SpriteOccluder2D is a godot plugin that adds special sprites that act like LightOccluders tthe adds two node types SpriteOccluder and AnimatedSpriteOccluder both calculate a LightOccluder2D on runtime

Just use SpriteOccluder as a normal Sprite and AnimatedSpriteOccluder as a normal AnimatedSprite

Epsilon is accuracy the lower it is the more accuracte but the lower it is the more resource intensive it is

Smoothing Experimental is by default off Its a simple algorithm that checks to see if theres a point in polygon that is to close to its neighbors if it is it snaps it inside its neighbors

it uses:

bitmap.create_from_image_alpha(image)
bitmap.opaque_to_polygons()

to create a polygon which later get used inside a LightOccluder2D if theres more then one polygon then it creates more LightOccluder2D's and then deletes them next frame
