Just want to say I'm glad vision modes are finally getting addressed and that I'm liking the general direction they're heading. I dislike having to spend 90% of my time in thermal as much as the next guy.
That said, I do have a couple complaints about the proposed thermal mode. First, blurring the mechs (especially at ~250m) looks awful and isn't at all realistic or necessary. I'd be on board with the blurred outlines more toward the extreme end of thermal's effective range though.
Second, and somewhat related, contrast (and thus effective range) in thermal should be both a function of distance and the target's heat relative to ambient temperature. The arbitrary max of 700m is, well, arbitrary. If there's a mech sitting 1200m out on alpine or frozen city riding 80%+ heat, it should be lit up on thermal like a beacon. A small, blurry blob of a beacon maybe, but very clearly a heat source. Conversely, mechs 500m+ out on caustic might be able to completely blend in with the terrain while still running at 50% or less heat. This is a bit of a tanget,I know, but I wasn't a huge fan of the change to thermal mode on caustic valley in the last patch, even if it is logical that thermal sensors can be calibrated to ambient temperature.
Also, I know it's already been acknowledged, but wow is the thermal data for alpine borked in that screenshot. Snow covered terrain nearly the same temperature as a walking fusion reactor?
Meanwhile, terrain and buildings on River City Night (a map with slightly above average ambient temperature) are black with very little contrast. I assume/hope the RCN shots are closer to the ideal.
All in all, I like the approach that NV is high contrast for terrain in low light conditions and thermal is high contrast for mechs on normal to low ambient temperature maps. I am curious how these redesigned vision modes play out both with the low visibility particles (blizzard, smog, etc) and what they look like in motion. More screenshots/video would be nice as development progresses. I'd also like to echo the request for a white hot/black hot toggle on thermal mode, assuming it's technically feasible and doesn't push thermal out of balance with respect to other vision modes.
