A demo made to show the capabilities of stencil effects in Godot.
The Outline and X-Ray examples are the built-in stencil modes provided by BaseMaterial3D.
The custom outline is an example of an effect made with the custom stencil mode.
A slightly more interesting x-ray effect.
ww_light.webm
An imitation of the simple lighting effects used in Wind Waker.
Very similar to stencil shadows.
Requires a 3-pass material with a script to enforce a global ordering.
campfire.webm
A very stylized flame effect achieved entirely with StandardMaterial3D.
