🎨 Convert GLSL Shaders to NestDrop/MilkDrop Presets | Step-by-Step Tutorial.

Hello creators! In this tutorial, I’ll show you how to convert GLSL shaders from ShaderToy into working NestDrop/MilkDrop presets using HLSL. Whether you're just getting started or exploring shader art for the first time, this guide will walk you through the entire process—from copying code to debugging and creating your own audio-reactive visuals!

🚀 What You'll Learn:
The difference between GLSL and HLSL
How to prepare your shader for MilkDrop/NestDrop
Formatting and debugging tips
Adding animation and audio reactivity

No advanced coding experience needed! Just a passion for creativity and a bit of curiosity.

🔧 Requirements:
NestDrop v2.0.1.0 or later
Notepad++ (or your preferred text editor)

Basic understanding of shaders (recommended)

📜 Python Line-Numbering Script (for comp_ lines):
from Npp import *
def add_incremental_prefix():
editor.beginUndoAction()
try:
Get the start and end positions of the selection
start_pos = editor.getSelectionStart()
end_pos = editor.getSelectionEnd()

Get the corresponding start and end lines
start_line = editor.lineFromPosition(start_pos)
end_line = editor.lineFromPosition(end_pos)

Loop only through selected lines
counter = 1 # Start numbering from 1
for i in range(start_line, end_line + 1):
line_start = editor.positionFromLine(i) # Get the position of the start of the line
prefix = "comp_{}=".format(counter) # Generate incremental prefix
editor.insertText(line_start, prefix) # Insert at the start of the line
counter += 1 # Increment counter for next line
finally:
editor.endUndoAction()
add_incremental_prefix()
