1. start from the template

copy shaders/utils/shader_template.gdshader and rename it. drop your file into res://shaders/ (flat, no subfolders).

2. tag it

@name         supersaw drift
@author       you@here
@description  one line

3. read the uniforms

uniform sampler2D prev_frame;
uniform float time_val, beat;
uniform float bass, mid, treble;
uniform float energy, onset, kick;

folder layout

ui/appearance/your_skin/
theme.tres       // colors
style.tres       // glass shader params
style.gdshader   // ui overlay
Geist.ttf        // optional font
icons/*.svg      // icon set

mix & match

users can run your theme with someone else's icons. all three pieces are independent — keep them honest.

live swap

no restart needed. change skin in Settings and every panel, button, and icon reloads instantly in place.
