`ui_r_tonemap`

rend2

Needs review. The inventory/provenance evidence is recorded, but some behavior, options, or attribution still lacks a direct user-facing source.

Engine-managed. The game maintains this value itself, so it is not a setting to change by hand: it is read-only after registration (CVAR_ROM); it is internal UI/engine state, hidden from every cvar listing (CVAR_INTERNAL); it is the menu's staging copy of r_toneMap, which the menu writes through when the change is applied and reads back when it is opened.

Controls ui_r_tonemap in the ui module. Consult the cited behavior reads before relying on values not listed here.
