Thought I'd ask scale modellers since wargame paint media is often full of shit shilling/overhyping, and the userbase sadly but understandably full of people who don't yet know what they're doing, but do any of you have experience with "makeup brush" style drybrushes? (or just makeup brushes) Artist Opus seem to be the brand pushing this the heaviest, but I've seen Army Painter do something similar.
I've never used anything like that but the gist seems to be that instead of horizontal brushes with hard bristles for edge highlighting as the GW heavy metal formula promotes, they're round and soft with a lot of soft bristles so as to approximate the soft feathered edges of an airbrush paint job with the added 3D effect of drybrushing to highlight just by targeting vertical sections.
So it's sold a lot as being good for edge highlighting/creating vertical highlighting, but also good for flat surfaces to create similar to airbrush soft/feathered transitions and layers. Like you could blend flat panels with them as much as targeting 3D detail.
It sounds plausible based on how makeup brushes work on IRL faces, but also a bit too good to be true. If they're good for anything else like weathering IDK that's good to point out too.
