Prismatica — Gradient & Liquid Fill Shaders

Gradient Shaders

Four gradient types — Linear, Radial, Angular, and Diamond — across every surface type and both pipelines.

Modifiers available on every gradient:

• Three-stop mid colour with configurable position
• Sine-wave colour animation between start and target colours
• Sharpness / power curve for hard bands or ultra-soft blends
• Horizon offset — shift the blend band without changing the angle
• Scrolling UV — flowing, lava, and liquid motion effects
• Procedural noise distortion (zero texture dependency)
• Dithered edge — dissolve-style boundary
• HDR brightness up to 3× (skybox up to 5×) for bloom-ready output
• Full 360° angle rotation on all gradient types

LiquidFill Shaders

Animated liquid simulation for 3D meshes, 2D sprites, and UI Canvas.

• Sine-wave surface with configurable speed, amplitude, and frequency
• Gradient liquid body with independent top and bottom colours
• Surface edge glow at the fill line
• Glass shell with rim glow (fresnel) and specular highlight — all toggleable
• UseGlass off mode for health bars, UI fills, and flat surfaces
• Wave amplitude fades cleanly to zero at empty and full — no surface artefacts
• 3D pass uses positionOS.x for the wave driver — no UV seam on capsule/cylinder meshes
• FillScale / FillBias for calibrating fill level on non-unit meshes

Skybox Shaders

Full-sphere gradient sky for both pipelines.

• All four gradient types via world-space view direction
• Procedural sun disc with configurable size, softness, HDR colour, intensity, corona glow, and falloff
• Brightness up to 5× for HDR/Bloom skies
• URP: assign as a standard Skybox Material via Lighting → Environment
• HDRP: fully integrated with the Volume system (Gradient Sky override)

UI Shaders

• Shape masking — assign any sprite to _MainTex; the gradient fills the exact alpha silhouette
• Sweep arc mask — cooldown rings, circular progress indicators, radial meters
• Metallic highlight streak — additive specular band for gloss/foil button and panel effects

Custom Inspector

• Live gradient preview strip in the Inspector
• Hex colour input (#RGB, #RRGGBB, #RRGGBBAA) — bidirectional sync with colour picker
• Collapsible sections — Pro and Light skin aware
• Contextual greying — irrelevant properties are greyed out automatically
• One inspector class covers all gradient shaders — no duplication

Setup & Compatibility

• Automatic pipeline detection — detects URP or HDRP on Editor load, writes the correct defines, no manual steps
• Include path auto-fixer — move the package anywhere in Assets/; shaders stay green
• SRP Batcher compatible — single CBUFFER per shader, confirmed in Frame Debugger
• shader_feature_local — unused variants stripped at build time, zero runtime branch cost
• half precision on mobile and WebGL — halves ALU cost on GLES3, Metal, and WebGL targets
• Zero texture dependencies — all effects are fully procedural

What's in the Box

• 10 shaders (5 URP, 5 HDRP) covering gradient, UI, skybox, and liquid fill
• 2 shared HLSL core files — one fix applies everywhere
• Custom inspector with live preview and hex input
• Automatic pipeline setup script with move watcher
• 7 demo scenes showing every feature end to end
• 7 demo scenes — no third-party dependencies required
