Handle kicker holes in playfield

[freezy]

Currently the playfield's material is cut-out, meaning that if there's no texture, it's opaque. This results in the kickers being virtually invisible. Here's a textureless playfield in Visual Pinball:

...which renders like that in Unity:

In most cases this shouldn't matter, since playfields are textured, and the kicker will be transparent.

A possible solution to implement the same behavior as Visual Pinball is to cut out the geometry of the playfield with a library like triangle.net.

look into using triangle.net with unity :

here are two c# unity files I created myself while using this exact library to make playfields with holes in them.

The Unity VectorGraphics package has triangulation support. It uses LibTess.net behind the scenes. https://docs.unity3d.com/Packages/[email protected]/manual/index.html
