Frames without PBR stick out like a sore thumb

For clarity: PBR, or Physical-Based Rendering, is a method of rendering materials in a game engine (or something like that). Basically it makes light reflection look more realistic, and allow for more different and detailed materials.

PBR was introduced sometime just before Update 15 hit in late 2014, and since then, almost the entire game has been converted to it. But man, when there's something that still uses the old rendering, it really sticks out. This mainly issues me in terms of Warframes.

As of now, Ash, Ember, Nekros, Nova, Nyx, Mirage, Rhino, Trinity, Valkyr, Vauban and Zephyr all lack PBR, giving them a very glossy plastic look, as opposed to the often used matte- and metallic-like rendering of a lot of PBR'd Warframes. So if you're using the Stock skin, Immortal skin (except Zephyr), or Alt Helmets on any of those Warframes, it's really going to stand out from everything else you're using, as well as a lot of environments, and in a time when Hydroid's PBR can literally be hotfixed in a week after some demand, you'd think it wouldn't be too hard just to squeeze out the few remaining ones.

Nowhere is the lack of PBR more noticeable and troublesome than on our beloved Warframes. This must be resolved, for the sake of the true endgame of Warframe!
