I had started a thread on the cockpit glass during the previous patch.
I don't think cockpit glass is where it needs to be yet, but it's better than I initially gave it credit for.
Try the same mech with cockpit glass enabled on a bright map, then on a dark map. There is still a subtle glare effect on the glass, you just don't notice it on the brighter maps. When everything is darker, you can see there is a shimmer on the glass that moves as you move your mouse around.
On some maps it seems like there is a bit of condensation on my Cheetah's canopy, I don't always notice it but it seems to show up on the wet maps. Maybe the water % stat on the map info page actually does something?

The recent dev vlog mentions getting rain to appear on the canopies as part of a future weather update, so getting dust, frost or rain interacting with the canopy would be cool.
My main request with the cockpit glass feature is that it is pretty equal from one chassis to the next, and that it doesn't limit visibility much. Right now some mechs have way too much green tint (bubble canopies get it around the edges, and mechs with flat panels and seams can get it on the side panels pretty bad). I know there is real world precedent for this, look at thick glass from an extreme angle (thick aquarium glass shows it well) and the color often shifts into green, but IMO it's too distracting here.
Play for a while with your default zoom (0.86x in my case) then zoom in to hit a target and the screen looks pink from the negative after-image of the green tint. Looks bizarre when Alpine turns into a bubble gum colored mountain. Almost expect Katy Perry to walk out and start shooting SRMs out of her bra or something
I like the idea of cockpit glass. I'm willing to take a slight performance hit and/or reduce visibility by a small margin to increase immersion, but this is just a bit too strong and switching it on/off for certain maps or mechs annihilates immersion.
