# 3D outline shader(s) for Godot
This repository contains shaders for drawing outlines around objects.
There are currently 3 shaders available. Pick and modify as needed.
Currently all outlines are drawn regardless if they're behind an object or not. I may fix this later.
## How it works
The shaders don't all work exactly the same but the general gist is as follows:
- First, it draws a couple of meshes as plain white on a black background inside a viewport.
- Then, it discards any pixels that are green (in the case of the blur shader, the other two check for a difference in the value of the red channel instead).
- Finally, it blurs the red channel.
## How to use it
The fastest way to get started is to add `res://addons/3d_outline/outline.tscn` to any scenes where you need an outline. Then, pass the `MeshInstance`s that need an outline to `outline_node`
