Everything read as wet plastic or glowing porcelain for two stacking reasons, both fixed centrally: - toonify() shipped every character/prop/weapon with a hot rim (0.45 over 65% of the silhouette) and broad stepped specular (0.25 @ shininess 24) — patent-leather highlights on any dark surface. Now a thin rim (0.15/0.4) and a small tight glint (0.06 @ 56); shader defaults match. - The LINEAR tonemapper clipped lit white surfaces (sun + ambient push facades past 1.0) and the glow pass bloomed the clip, so buildings glowed like porcelain. Switched to FILMIC with white=2.4: near-linear through the cel bands (they stay crisp), soft shoulder above 1.0. Glow threshold 1.1 -> 1.45 so only genuine emissives (neon, tracers, plasma) bloom. - Saturation 1.22 -> 1.3 compensates filmic mids — vibrancy unchanged. - Neon Alley: ambient 1.7 -> 1.35 / sun 2.2 -> 2.5 — the shoulder no longer hides the ambient lavender cast, so let the sun shape the facades.
