SUMMARY When you have mypaint brush pack, these are inside zip files and themselves in folders. If you copy paste this folder into the preset folder, Krita will be able to find the brushes, but not able to load them properly STEPS TO REPRODUCE 1. Get a mypaint brush pack. 2. Unzip it into the presets folder. 3. Load up Krita OBSERVED RESULT Krita will recognize the brushes, but load them with a red thumbnail and not load the brushes when selected. EXPECTED RESULT Krita will try to load these brushes from the subfolder they're in. ADDITIONAL NOTES - Krita will behave the same way with removed database. - We should check if Krita loads other resources inside subfolders properly.

That's kind of unavoidable since the icons and the brushes are in two separate files, and our whole resource system goes crazy when that happens. It's also the reason why we cannot handle myb files in bundles, since the resource itself has no way of figuring out where the partner file is. The only solution I can imagine is making a kmyb file format that combines the myb and the png in one file, or puts the myb in the png, and convert my files when krita first encounters them.
I would first worry about the fact that the presets themselves don't load properly (I guess I wasn't clear enough, but selecting these presets leads to the default mypaint preset being selected), before worrying about the thumbnails. I am also not sure if we should worry too much about the thumbnails, when all that's necessary is for them to be stuck into the image section in the database.
I'm pretty sure that no resources put in a subfolder will load correctly at the moment.
Can you please check? I believe I fixed it in a6077decd3abd23f and cfac35715743edcb . I haven't checked with MyPaint presets in particular, but with other resources that didn't work before either.
