How to Convert Csp Brushes to Procreate
StyleFrame Team8 min read
Procreate cannot open Clip Studio Paint's .sut files, so there is no direct import. You have two realistic options: run the .sut through a third-party converter that rebuilds it as a native Procreate .brush or .brushset, or rebuild the brush by hand in Brush Studio from an exported tip image. Because the two brush engines work differently, expect a close approximation rather than an identical brush, and plan on some tuning either way.
Why CSP brushes don't import into Procreate
Procreate supports its own .brush and .brushset formats and can import Photoshop .abr files. It has no reader for Clip Studio Paint's .sut. Procreate's team has said it added .abr support because so many brush makers build for Photoshop, and that supporting every other app's format is a harder case. Users have been asking for CSP support for some time, so don't plan around it arriving.
The formats also describe different engines. A .sut stores tip and grain images, stroke path behavior, pressure and tilt curves, texture settings, and color-mixing behavior. Procreate has its own equivalents for some of these and nothing for others. That is why every method below is a translation rather than a copy.
Method 1: Use a .sut-to-.brush converter
The fastest route is a web converter that reads the .sut and writes a Procreate archive. Brushfactory is one example. It says it carries over tip and grain images, stroke path settings, pressure and tilt response, texture settings, and linked materials. It exports single brushes as .brush and multi-brush files as .brushset.
The workflow looks like this:
- Export or locate the
.sutfile on your computer. Brushes downloaded from Clip Studio Assets or a creator's store are usually easiest to find. - Upload it to the converter and choose Procreate as the target.
- Download the
.brushor.brushsetfile. - Send it to your iPad with AirDrop, iCloud Drive, or a cloud folder, then tap it. Procreate imports it into your brush library.
Some practical notes:
- Check what was adjusted. The service says its result screen names any setting with no exact Procreate equivalent. Read that list. It tells you where to start tuning.
- Smudge and wet behavior is approximated. Brushfactory says these map to the closest available response, so test mixers and blenders first.
- Free tiers have limits. The service offers a limited number of monthly conversions on a free account, with batch conversion on a paid plan. Convert your most-used brushes first.
- Understand the upload. You are sending brush files to a third party. The service says uploaded files are deleted after processing, but if the brushes are licensed or under NDA, read the terms first.
Method 2: Rebuild the brush manually from its tip
If you don't want to use a converter, or the converted brush doesn't behave well, you can rebuild the brush in Procreate's Brush Studio. This takes longer but gives you full control. The same approach works for brushes you own and want to adapt.
Step 1: Capture the brush tip
In Clip Studio Paint, open the brush's sub tool detail settings and go to the brush tip or shape section. Open the tip image so it is displayed at a readable size, then capture it. A screenshot is the simplest method, though a clean export of the material image is better if you have access to the source.
Step 2: Clean it into a usable shape
The shape source needs a clean, high-contrast image of the tip.
- Bring the capture into Procreate or any image editor.
- Select the tip shape, remove the surrounding interface and background, and fill the shape solid white on black.
- Check the edges for stray pixels. A dirty edge shows up on every dab.
- Export it as a PNG, or import it from your photo library.
Step 3: Create the new brush
- In Procreate, open the Brush Library and create a new brush.
- Open the Shape section, tap Edit, and choose Import to load your PNG as the shape source.
- If the original brush used a paper or texture grain, repeat the process under Grain with that texture.
- Rotate or invert the source if the stamp looks flipped.
Step 4: Recreate the dynamics
Now match the behavior. Open CSP's brush settings next to Procreate and work through them in order:
- Spacing and scatter: match stroke spacing, jitter, and scatter.
- Taper: set start and end taper.
- Pressure response: map size and opacity to Apple Pencil pressure, and adjust the pressure curve until light and heavy strokes feel like the original.
- Opacity and flow: set the maximums so a full-pressure stroke matches.
- Texture behavior: decide whether the grain moves with the stroke or stays fixed to the canvas.
Paint the same test stroke in both apps, such as a fast line, a slow curve, and a heavy fill, and compare them side by side. Adjust until they match to your satisfaction, then duplicate and rename the brush so you keep a clean copy.
Method 3: Ask for an .abr version
If the brush came from a creator who also works in Photoshop, check whether they offer an .abr version. Procreate imports .abr files, though not every setting from the original brush may carry over. You may still need to adjust settings, but this is often less work than rebuilding from a screenshot.
What won't translate well
Set expectations before you invest an afternoon in conversion. Procreate users and brush makers regularly point to gaps between the two apps:
- Color mixing and average blending. CSP's mixing brushes blend colors in a way Procreate's standard blending doesn't replicate. Converted mixers may look right in shape and still behave differently on the canvas.
- Dual-color brushes. Some CSP brushes map light values of a tip to one color and dark values to another. There's no direct Procreate equivalent.
- Image-hose or nozzle brushes. Brushes that stamp full-color images in sequence rely on features Procreate doesn't offer in the same form.
For these brushes, the better strategy is often to find the closest Procreate brush and tune it, or to keep that part of the work in CSP and bring the finished art across as layers.
Test before you commit to a project
Before relying on a converted brush in production, run through a short checklist:
- Paint at three sizes, since a brush that looks right at 40 px can fall apart at 4 px or 400 px.
- Test light, medium, and hard pressure, plus tilt if you use it.
- Check edge quality and grain at your actual canvas resolution and DPI.
- Test over transparent backgrounds and over colored layers.
- Export a PNG with alpha and check it in your compositing app, since fringing and premultiplication issues show up there first.
Licensing and brush ownership
Converting a file doesn't change who owns the brush. Many brush packs from Clip Studio Assets and independent creators have terms covering redistribution, commercial use, and modification. Converting for your own work is generally different from sharing the converted file, but check the license. Never redistribute a converted brushset you didn't make.
Where this fits in a motion pipeline
For motion designers and animators, the brush is usually a means to an end: hand-drawn frames, textured mattes, ink-style elements, or painterly keyframes that get animated or composited later. Procreate and CSP are both common places to make those assets, and the practical question is how to get the look into After Effects or Nuke.
The simplest path is to paint your frames or elements in Procreate, export them as PNG sequences or layered files, and bring them into After Effects or Nuke as usual. If you rely on a brush-specific look but can't reproduce it exactly after conversion, you have another option: paint a few key frames in whichever app has the brush, then use those frames as references.
This is where Styleframe can help. It is an AI video and motion tool. If your look lives in a CSP brush you can't port, a few painted reference frames may help carry that texture into motion. This doesn't replace brush conversion for people who need to paint in Procreate with a specific brush, but it removes a hard dependency on one brush file when the goal is a consistent look across moving frames.
Quick decision guide
- You have a few
.sutbrushes and want them fast: use a converter, then tune. - The converter result feels off or you want full control: rebuild from the tip image in Brush Studio.
- The creator also sells for Photoshop: import the
.abrversion. - The brush depends on color mixing or nozzle behavior: find a close Procreate alternative, or finish that part of the work in CSP.
- You need the look to carry across animated frames: paint reference keyframes and use them as style references in your motion pipeline.
FAQ
Can Procreate import .sut files directly?
No. Procreate doesn't read .sut, so the brush has to be converted to .brush or .brushset, or rebuilt manually.
Will a converted brush feel identical? Not always. Procreate and CSP use different engines, so shape, spacing, and pressure response often convert well, while mixing and smudge behavior is approximated.
Can I go the other way, from Procreate to CSP? Yes, but the same limits apply. The usual method is to export the brush tip as an image, register it as a material in CSP, and recreate the dynamics by hand.
Do other apps have similar converters? Yes. Community tools exist for importing Procreate, Photoshop, and CSP brushes into Krita and Blender, with results that vary by brush and version.
