-# GLSL Shader Sources
-
-This folder contains the GLSL fragment shaders extracted from blueprint JSON files for easier editing and version control.
-
-## File Naming Convention
-
-`{Blueprint_Name}_{node_id}.frag`
-
-- **Blueprint_Name**: The JSON filename with spaces/special chars replaced by underscores
-- **node_id**: The GLSLShader node ID within the subgraph
-
-## Usage
-
-```bash
-# Extract shaders from blueprint JSONs to this folder
-python update_blueprints.py extract
-
-# Patch edited shaders back into blueprint JSONs
-python update_blueprints.py patch
-```
-
-## Workflow
-
-1. Run `extract` to pull current shaders from JSONs
-2. Edit `.frag` files
-3. Run `patch` to update the blueprint JSONs
-4. Test
-5. Commit both `.frag` files and updated JSONs
