Features

This project provides a couple of nodes:

• SugarLayer (CanvasLayer) - works with both - 2D and 3D scenes
• SugarQuad (MeshInstance with 1x1 quad) - works with 3D scenes only

which apply selected effect to the entire screen:

• None - no effect
• Blurr - applies blurr effect
• Pixelate - pixelate effect - provides a pixel-art look in runtime
• Grayscale - changes colors to grayscale
• Sepia - applies sepia effect
• Grain - adds/removes/mixes-in a grain (open simplex noise) effect
• Palette - changes color palete (with optional dithering effect)
• Lut - changes color space using lookup table (LUT)
• Darken - makes scene darker
• Depth - shows depth buffer
• Outline - draws the outline using depth buffer (it gives a poor effect with artifacts for now)

Caveats

This Godot addon is experimental and it may even crash the entire editor. I recommend to use it with care - for prototyping purposes only.
