Featured

Use when setting up URP (or choosing URP vs HDRP), configuring URP assets and quality tiers for PC and phones, lighting a stylized or realistic Unity scene (sun, sky, baked or mixed lightmaps, Shadowmask, Adaptive Probe Volumes, reflection probes), or fixing blurry shadows, light leaks, gray bakes, washed-out images, tonemapping and grading, bloom too expensive on mobile, TAA, STP or MSAA choices, GPU Resident Drawer setup, shader warm-up hitches, or a custom shader that vanished or lost its baked light.

Skill Content

# Rendering and lighting (lighter / graphics TA) Expert lighting in Unity is a measured loop: fix exposure, light to anchors, bake, grade, judging every stage from the same camera bookmarks with numbers (gray cards, clipping, bake memory, native passes) before taste. This skill drives URP 17.3 on Unity 6.3 from code; everything here ran in Unity 6000.3.21f1 on an Apple M5 Max (Metal) on 2026-09-24. If a sibling skill named here is missing from your available skills, ask the user to install it (`npx skills add scenario-labs/skills --skill <name>`); unattended, proceed from tool schemas and flag the gap. **REQUIRED BACKGROUND:** scenario-unity-expert (channels, `ut_run`, `AgentCapture`, `AgentProfile`, `ut_review`, 6.3 traps). ## Stance (the expert delta) 1. **Exposure first, lights second** (Pierre Yves Donzallaz, yqCHiZrgKzs [00:20:21]). URP 6.3 has Fixed exposure only: one Post Exposure per zone, lights solved from an 18% gray card (the unaided sun 2.0 read +1.03 EV with no tonemapper; the solved 0.98 read +0.16 EV under Neutral). 2. **Expect gray after baking; fix it in post under the tonemapper you chose early** (Kyle Banks, 1agSNKuAfTM [00:04:58]; PYD [01:01:29]): Neutral for lookdev; contrast, saturation, Shadows Midtones Highlights pushed too far, then dialed back. ACES darkens (K3-wPnhmDi4 [00:54:50]; measured -1.4 EV): re-solve exposure under it. 3. **Shadow distance before resolution** (6.3 Manual; HCXCmHgV7Sk [00:15:32]): 1024 over 10 m beats 2048 over 40 m.

scenario-blender-lighting-rendering

Use when lighting, rendering or compositing in Blender: light a character, product or hero shot, interior at dusk or night, three-point or motivated lighting, sun and sky, HDRI, EEVEE vs Cycles settings, light leaks or noise, flat or muddy renders, subject not standing out, AgX/ACES color management, render passes, EXR, light groups, bloom and vignette in the 5.x compositor, rule of thirds and value checks, toon/NPR looks, or judging a render like a lighter.

scenario-unity-shaders

Use when a Unity 6.3 URP task involves shaders: hand-written HLSL, Shader Graph water, toon, dissolve or outline, Custom Function nodes, a renderer feature or full-screen effect on Render Graph, compute shaders, shader variants, keywords, stripping, Shader Build Settings, PSO warm-up, or shader cost; or when a material turns pink or invisible, casts no shadow, ignores extra lights under Forward+, an effect 'does nothing', the game stutters the first time something appears, or builds bloat with variants.

scenario-unity-2d

Use when building a 2D game in Unity 6.3 URP: pixel-art or HD sprite import and PPU, sprite atlases, Tilemaps, Rule Tiles and reskins, the 2D Renderer and 2D lights with normal maps, 2D animation, a platformer or top-down controller ("make a platformer controller that feels good", coyote time, jump buffer, one-way platforms, spikes), Pixel Perfect Camera, a follow or room camera, hit stop and screen shake; or when pixel art looks blurry or shimmers, tiles show seams, 2D lights do nothing or cost too much, the jump feels floaty, or the camera loses the player when falling.
