HTrace WSGI composites indirect lighting after post-processing using the GBuffer albedo/occlusion of the player's stock URP GBuffer pass. That pass knew neither the painted-height AO semantics nor the brightness/saturation grade, so desaturated paint reappeared fully saturated in shadow/indirect light and painted height modulated GI with the raw 0.5-centered value. - PlayerCamoShared.hlsl (new): single source for camo knobs, ApplyPaintedHeightSurface and ApplyCamoBodyGrade shared by both passes - PlayerCamoGBuffer.hlsl (new): CamoGBufferFragment = URP 17.3 Lit GBuffer fragment + height-AO remap on occlusion + grade applied to albedo - PlayerCamoLit.shader: GBuffer pass now uses CamoGBufferFragment - PlayerCamo.hlsl: consumes the shared helpers (forward path unchanged) Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

// Camo variant of URP's LitGBufferPassFragment. Include AFTER LitGBufferPass.hlsl (reuses its

|
|
// The project renders FORWARD, so this GBuffer pass has exactly ONE consumer: HTrace WSGI renders
|
|
// its thin GBuffer through the "UniversalGBuffer" tag and its GI composite multiplies the traced
|
|
// irradiance by GBuffer0.rgb (diffuse albedo) and GBuffer1.a (occlusion), ADDING the result after
|
|
// post-processing - i.e. after the forward pass's camo grade already ran. Two camo hooks keep that
|
|
// injected indirect light consistent with the graded forward look:
|
|
// 1. ApplyPaintedHeightSurface: forward AO semantics for the painted height (neutral 0.5 -> AO 1)
|
|
// instead of the raw 0.5-centred height value in GBuffer1.a, + the relief normal.
|
|
// 2. ApplyCamoBodyGrade on the albedo: brightness/saturation follow into the injected GI, so
|
|
// desaturated paint stays desaturated in shadows / under indirect light.
|
|
// Everything else is a faithful copy of URP 17.3 LitGBufferPass.hlsl's fragment.
