About this asset

Luminex is a production-grade volumetric fog and lighting system built on a froxel (frustum voxel) pipeline — the same architecture used in AAA titles and modern game engines.

Fog density, light scattering ,shadows, and temporal reprojection are computed entirely in GPU compute shaders. This is not a post-process overlay. It is a complete atmospheric rendering stack.

Compiling compute shader variants can take at least 5/8 min to fully complete , be patient ! It is only a thing to do once . ( quickest compil time will be implemented for v1.1 )

Auto pipeline configuration and defines , you will have almost nothing to care about .

274 automated tests. Clean, well-structured codebase with full constant coverage and no magic numbers. Three hotfix patches since launch. Actively maintained — more HDRP scenes and new features are already in development for upcoming updates.

MOBILE and HDRP are in early experiment , you can try it but issues can pop .

HDRP is an UNITY 6 ONLY FEATURE !

REQUIREMENTS Unity 2022.3 LTS or Unity 6. Compute shader support required (DX11+, Metal, Vulkan). Burst package.

Dense roadmap with Third parties integration , enhancements and new features is already on tracks .

Technical details

SUPPORTED PIPELINES :

  • Universal Render Pipeline (URP) — full support
  • URP RenderGraph (Unity 6) — full support
  • HDRP — coming FREE in v1.1
  • VR / XR — coming FREE in v1.2

VOLUMETRIC FOG

  • Height fog with Linear, Exponential, and Exponential Squared falloff.
  • Cloud formation layer.
  • Domain-warp, curl, multi-layer, and morphing noise animation.
  • Terrain-following fog baked from Unity Terrain heightmap.
  • Distance fog in radial and planar modes.
  • Per-fog-volume density blend.
  • Multiple simultaneous cameras supported.

LIGHTING

  • Point, spot, directional, area (rect and disc), and tube beam lights — all with full volumetric scattering.
  • Henyey-Greenstein and Dual-Lobe phase functions.
  • Per-light scattering color, intensity, anisotropy, cone tip radius, and local density volumes.
  • Light probe ambient contribution.
  • Blue noise temporal dithering.

SHADOWS

  • Custom shadow atlas with variable-resolution bin packing and score-based slot allocation.
  • Experimental Variance Shadow Maps (VSM) with Gaussian blur and Chebyshev sampling (only spot URp for now ).
  • PCF for spot and point lights.
  • Up to 4 cascade shadows for directional lights with temporal scheduling and texel-snapped stabilization.
  • Full CIE LAB color-space encoding for perceptually accurate colored and translucent shadows (stained glass, foliage).
  • Adaptive shadow cache skips unchanged static sources.
  • Absorbtion accumulation and surface tint mix for stacked transparent objects ( urp only )

TUBE BEAMS

  • True constant-radius cylinder light shafts with beam-surface reflections, mirror tracing, and a complete interactive beam puzzle system (BeamTarget, BeamTerminator, LightPuzzleManager).
  • DENSITY PRIMITIVES 10 SDF shapes: Sphere, Box, Capsule, Cylinder, Ellipsoid, Torus, Cone, Pyramid, Hemisphere, Octahedron.
  • Add, subtract, and multiply blend modes.
  • Per-primitive noise and emission.

SURFACE TINT

  • Colored light projection onto opaque and transparent surfaces for stained glass effects. Bilateral depth-aware blur with dilation pass.
  • GPU DUST Compute-shader particle system with curl noise motion.
  • Full LAB shadow integration on dust particles.

PERFORMANCE

  • Temporal reprojection with camera-motion-aware feedback reduction.
  • Adaptive quality scaling.
  • Job System culling with optional Burst acceleration.
  • Sparse shadow update scheduling.
  • VolumetricLOD for per-object distance-based quality reduction.
  • Quality presets: Low (522K froxels), Medium (1.4M), High (2.7M), Ultra (5.2M), Custom.

EDITOR TOOLING

  • Full custom Inspector with progressive disclosure.
  • Preset save/load system.
  • Reflection-based validation guards.
  • Shadow atlas, noise atlas, and surface tint debug visualizations.
  • GPU timing overlay.
  • Lot of demo scenes included.
