Interface TonemapParams

Whether this component is enabled.

Linear scale applied to HDR scene colours before tonemapping. Values above 1 make the scene brighter and push more of the range into the tonemap curve; values below 1 darken.

Default is 0.5 — chosen so ACES midtones stay below the no-tonemap (detailed profile) reference, leaving headroom for HDR specular peaks (sun, smooth-metal reflections) to read as bright accents rather than washing into the rest of the frame.

Tonemap curve. Default is "aces" — ACES Filmic — so HDR scene values roll off into displayable range without clipping. Switch to "reinhard" for a softer/cheaper curve, or "none" for an identity copy that matches the pre-HDR look.

Supersampling factor. The scene (and all scene-phase FBOs) are rendered at canvas * renderScale resolution, then the tonemap pass samples that larger texture with LINEAR filtering when compositing to the canvas — giving free box-filter downsampling antialiasing. Also helps subpixel aliasing that FXAA can't reach.

Range [0.5, 4.0]. 1.0 = no supersampling; 2.0 = 4× the fragment work (rendering 4 pixels for every 1 displayed). Default is 1.0.

If true, the final colour is gamma-encoded with pow(c, 1/2.2) before writing to the canvas. The renderer's albedo textures upload as SRGB8_ALPHA8 (sRGB-source, linear-sample) and shading runs in linear space, so the swap-chain write needs the inverse encode for the canvas to display gamma-correct. Defaults to true; only set false if you have a reason (e.g. a custom downstream encode in your own canvas pipeline).
