I recently downloaded some brush bundles for krita, from the Resources forum on this site.
Some of the brush tips and patterns used by these bundles are showing up (though not all), but none of the brush presets are showing up, either in the Resource Manager or the Brush Presets menu. These were all downloaded as .bundle files, intended for Krita, and clearly intended to have presets in them. The bundles show up and are active, but not the brushes.
To clarify, all the brush presets from the standard brushes are present, just not the ones I downloaded.
As @Takiro already correctly said, without the names of the bundles in question it is nearly impossible to give a correct answer.
Only the standard question, did you already restart Krita twice after importing the bundles to fully update the database?
I’ve just had a look at the glitter-gel-pens bundle and it all works but has a problem.
The bundle has one brushtip file and that file is called A_eroded-cercle-anim.gih which is a nice working animated brushtip file.
In the brush editor, the three brush presets of that bundle all work and are using the pattern provided by the bundle but they are using a brushtip called A -18 round eroded anim
The reason for this is that the file called A_eroded-cercle-anim.gih has internal data that gives the actual ‘name’ of the animated image as A -18 round eroded anim
This can be seen at the start of the .gih file:
You can do this with .gih files. The .gih file is a container that describes an animated image, i.e. the animated image name, the organisation and control inputs and then the individual images content.
This is why I always give .gih files the same name as the internal animated image name
The difference between brushtip file name and brush ‘identity name’ may be causing a problem for the Manage Resources facility making it unable to display the brush tip in its listing.
That would be easy enough to test by making some simple example animated image files.
If so, this is a bug that should be reported.
For other problems with bundles linked in this topic, there may be similar situations and these should be examined to find out what may be happening.
Sadly, I don’t have time to do that so I hope that someone else can do it.
