2023-10-13DRTVWR-592: Don't read UVs for PBR terrain in single-plane case - works out ↵Cosmic Linden
to be more expensive than triplanar in some cases, and UVs are already trivial

2023-10-13DRTVWR-592: (WIP) (has debug) More rigorous definition of usage vector for ↵Cosmic Linden
triplanar that avoids possible case where 1 = 0.9999, which gets rounded down to 0 on int cast

2023-06-01DRTVWR-559 Revert skies to be very close to release and disable tone mapping ↵RunitaiLinden
when probe ambiance is zero. Hack for desaturating legacy materials has been removed for performance and quality reasons. Adds a new setting for auto adjusting legacy skies. This is the PBR "opt out" button. If disabled, legacy skies will disable tonemapping, automatic probe ambiance, and HDR/exposure. If enabled, legacy skies will behave as if probe ambiance and HDR scale are 1.0, and ambient will be cut in half. HDR scale will act as a sky brightener, but will automatically adjust dynamic exposure so the sky will be properly exposed. If you want relatively even exposure all the time, set HDR Scale to 1.0. If you want a high range of exposures between indoor/dark areas and outdoor/bright areas, increase HDR Scale. Also tuned up SSAO (thanks Rye!). Reviewed with Brad.
