Clip Studio Assets vs MyPaint Brushes

Clip Studio Assets is a catalog for finding, downloading, and publishing materials for Clip Studio Paint. Its collection includes brushes, image materials, poses, 3D objects, gradients, color sets, workspaces, and Auto Actions. Free materials are available; individual paid materials may be priced in Clippy or GOLD, which are required to download them. A Clip Studio account is required to download materials or to publish and edit them. Users can access the service through Clip Studio Start or a browser on a tablet, PC, or smartphone, with Android, iOS, macOS, web, and Windows listed as platforms. Clip Studio Paint version 4.2 and later can automatically install downloaded tools, color sets, gradient sets, workspaces, and Auto Actions; other software requires extracting downloaded ZIP files. Anyone can upload Clippy materials, while GOLD materials are restricted to qualified creators and earn royalties based on price and download count. Uploads must belong to the submitter, and materials made with AI image-generation technology are prohibited. CELSYS says it may remove materials or suspend accounts without prior warning.

MyPaint Brushes is a free downloadable brush-data package for MyPaint and other applications that use libmypaint. The master branch contains brushes intended for libmypaint 2.x. For libmypaint versions below 1.5, the project recommends using the v1.3.x branch or a v1.x release instead; listed releases include v1.3.1 for libmypaint 1.3 or later and v2.0.2 for libmypaint 1.5 or later. The brush files use the .myb format, and commercial use is permitted. Application developers can locate the brush directory through pkg-config: C and C++ programs use the MYPAINT_BRUSHES_DIR macro, while other languages can use the brushesdir variable. Building and installing the package uses autogen.sh, configure, make, and make install. Historical SCons scripts are included for SCons 2.x, but do not work with SCons 3. The official brush data uses public domain or CC0 1.0 licensing. Installation scripts and other non-brush-data components use GPL-2+ licensing. The v2.0.2 release note says its changes reduce preview icon file sizes and that v2.0.x brushes generally need libmypaint 1.5 or later to work correctly.
