CSP → Procreate Brush Converter

⚠️ With the release of 5.4 new brush features have been added. This might: 1. break the script. 2. theoretically improve future script iterations that implement these new brush settings during conversion. ⚠️

Convert Clip Studio Paint .sut brushes to Procreate .brush or .brushset files with automatic mapping for many brush settings.
Supports both CLI usage and standalone executable mode with file picker.

⚠️ Note: Some CSP-specific functionality has no direct equivalent in Procreate and cannot be mapped. This script is by no means a perfect 1:1 conversion. However, it automates many annoying parts of the conversion and with some setting changes after the import, many brushes can be recreated.

Features

• Automatic brush setting mapping for:
  • Stroke Path (spacing, jitter)
  • Taper (pressure & touch)
  • Shape rendering
  • Wet mix
  • Basic brush properties (opacity, rotation, scatter, flip, etc.)
• Preserves multiple brush tips in a .brushset
• CLI or double-click executable usage
• Executable works on Windows and macOS (with Python or packaged exe)

Usage

1. Command-line

python csp2procreate.py mybrush.sut output_directory

2. Packaged Executable

• Double-click the executable
• Select your .sut file and output directory

Output

• Single brush → .brush file
• Multiple brush tips → .brushset bundle

Limitations

Some CSP brush features cannot be fully represented in Procreate, including:

• Special texture effects
• Dynamic color blending beyond Wet Mix
• Custom pattern behavior
• Multi-brushes and Pattern Sequencing
