For me, it just takes a few minutes now to fully mod them the way I like to take full advantage of the shaders (mostly m3d, dds, and xdp file edits), but I'll admit it was pretty daunting at first.
I've probably "fixed' a couple of thousand individual aircraft over the years, but getting permission to publicly upload them all would be problematic to say the least.
Then there's the issue of the original publisher's artistic intent perhaps being different from mine. For example, they might want more or less gloss to show on their model than I do. In particular I like a bit more shine on the cockpit surfaces to provide as much 3D contour shaping as possible. For me this really enhances the feel of being in the pilot's seat, but typically the original intent is to have them look less like a new factory finish. On the other hand many people often want the exterior to look more like a museum restoration with fresh paint and polished surfaces, and I tend to make them look more like they've been parked outside for a while and the newness has worn off.
Which leaves us with my attempts to carefully document here how things are done, and to provide what support I can to anyone who seeks help in making their own mods to reap the various benefits of the new shaders.
