Keep the native brush pack intact
A PRBR file is one Infinite Painter brush; a PRZP is a brush pack. Keep the PRZP file intact. Do not unzip it or pull out individual brushes before import. If a separate outer download ZIP contains the native files, follow the package notes to extract only that outer wrapper. Keep the original files.
These native formats are not Photoshop ABR or Procreate brush files. Match the resource’s tested Infinite Painter version and device. A compatible file type does not establish that every device or stylus will give the same stroke.
Import through Options → Import → Files
Open the Options menu and choose Import. Select Files as the source, locate the saved PRBR or intact PRZP, and import it. Use Files rather than the image gallery to select a native brush file.
An imported PRBR brush appears in Downloads. A PRZP pack gets its own custom folder in the brush list. Look in these places before importing again, and check the app version and device requirements in the package notes.
Find the pack and compare one brush
Try one imported brush on a spare canvas at your intended size, making a stroke and a texture patch. If the package includes a sample, match its size, opacity, and listed settings when comparing. If pressure or tilt matters to the brush, check the device and stylus in the resource notes. Keep the original PRBR or PRZP while adjusting a working brush.
If the pack does not import or brushes are missing
Confirm that the PRZP is complete and has not been unzipped outside Infinite Painter. Use Files, check the new brush folder, and compare the app version with the package notes before trying again. Record the filename, version, device, and failed step. For a Brushory package, sign in to report the problem, or contact support if its public resource page is unavailable.
