You need to activate the “Krita 3 Default Resources.bundle” to find more of these brushes, that bundle is usually deactivated by default in Krita versions above 5.0.x, it can be done under ‘‘Settings’’ >> ‘‘Manage Resources…’’. But also in the “Krita 4 Default Resources.bundle” are shape/fill-brushes
There are a few bundles offering such brushes, Artmessiah, Cazu (Pablo Cazorla), deevad-bundle_23-01.bundle, fullerhill_art - Crunchy Brushes.bundle, The EO Pencil Case, EZSaeger - Mojo Tools 1.0.bundle (license CC-BY-SY from our member saeger but not in the bundles he shares here) & Mojo Moo for comics in the Mojo-Moo-Draw.bundle, Nylnook, Rakurry, GDQuest, Iruhas 6 main brushes, Raghukamath, Version 6.0 of wojtryb’s “Wont teach you to draw” brushpack . I hope that is enough for you? Keywords to find thesebrushes are shape & alchemy but Cazu has also “Concept Shader Flat” & “Draw Mask Vector”, fullerhill_art has “CB Snap”, saeger has “Eraser-Trimmer” & “moo-draw-oknife”, raghukamath has “pack01 fill”, Rakurry “rxd) Fillbrush” & “rfi) Magicfill”.
Another good way to identify and find installed shape brushes is to hit F5 and open the preset view on the left (the little leftward pointing arrow below the preset-thumbnail), then select the shape-engine from the available brush-engines via the drop-down menu.
