adminandClaude Opus 4.8 b5bd1fdb8b Rework the camo shader to flatten toward darkness, drop FormSoftness 
Rebuild the camo controls around hiding a painted player in a dark scene. _HalfLambert is now a two-segment curve (0 = no effect / URP Lit, 0.5 = classic half-lambert soft terminator, 1 = fully flat) and a companion _HalfLambertBrightness (-1..1) additively shifts the flattened diffuse so the body tone matches the scene. _SpecularDampen still scales down the direct highlight. The view-coupled _FormSoftness normal-bend is removed entirely (it flipped light/dark with the camera); all knobs are now term-based and view-independent, and stay byte-identical to URP/Lit at their no-op values.

Raw Blame History

// Drop-in clone of "Universal Render Pipeline/Lit" (URP 17) for the PLAYER avatar that adds
// camouflage lighting: the player stays lit by the scene (matching its surroundings) but its 3D
// form is de-emphasised, so a correctly painted avatar is harder to spot. See PlayerCamo.hlsl.
//
// Faithful copy of URP's Lit.shader - same properties, keywords and includes, so material values
// transfer 1:1, the Lit inspector keeps working, and the runtime MeshPainter (which only sets
// _BaseColor / PBR keywords on the material instance) is unaffected. The ONLY change is the
// ForwardLit pass: its fragment is CamoForwardFragment, which reimplements URP's forward shading
// while delegating GI / shadows / clustered lights to URP and applying the camo knobs. All
// other passes (ShadowCaster, GBuffer, DepthOnly, DepthNormals, Meta, ...) are stock URP/Lit.
