Infinite procedural volumetric nebula for HDRP. Endless cinematic space flythrough with emissive core, drifting stars, real-time performance modes, and one-click setup. Loop-ready for video.Currently only HDRP. Stay tuned for updates.Nebula Flight — Infinite Volumetric Space Flythrough for HDRPFly forever through a living, glowing nebula. Nebula Flight is a fully procedural HDRP volumetric system that renders an endless cinematic journey through cosmic gas, dust lanes, and a burning emissive core — with a drifting star field streaming past you.No meshes, no textures to bake, no loop seams to fight. Just press play and drift.Everything runs as a single fullscreen HDRP Custom Pass with the entire raymarch written in HLSL, so it stays sharp at any resolution and renders straight to your camera. The camera never actually moves — the noise domain flows around it — which means the flight is genuinely infinite and never snaps back to a start point. Perfect for hypnotic, meditative footage that can run for hours.Built for creators who need atmosphere on demand: YouTube ambient channels, meditation and sleep videos, live wallpapers and screensavers, menu and title backgrounds, sci-fi cutscenes, VJ loops, and warp-jump / star-system transition effects between scenes.Tuning is immediate and visual. Shape the gas density, dust filaments, and hue variation; set your color ramp from deep blue through magenta into hot orange; dial the core's glow, cavity, and Beer-Lambert dust shadowing. Two performance switches keep it real-time while you work — an internal Resolution mode (Full / Half / Quarter) and a Quality preset (Preview / Final) — then flip to Full Fully procedural volumetric nebula — no meshes, no baked textures, no seamsInfinite continuous flythrough with a static camera (drifting noise domain, no loop snap)Variant A lighting: analytic inverse-square emissive core + Beer-Lambert dust self-shadowingSingle fullscreen HDRP Custom Pass, complete raymarch in HLSL — resolution-independentGPU-instanced billboard star field with per-star HDR color, atlas cell, and twinkle4-stop color ramp (low → mid → high → core) with spatial hue variationPerformance modes: internal Resolution scale (Full / Half / Quarter) for big real-time winsQuality presets (Custom / Preview / Final) to switch between fast tuning and clean captureOne-click scene setup: Custom Pass + Bloom/Vignette/Film Grain post + star fieldDeterministic frame-locked playback for artifact-free Unity Recorder capturesFull HDR pipeline tuned to feed Bloom for the glowing core and starsOptional right-mouse free-look camera component includedClean, comment-free HLSL + C#, assembly definitions, HDRP-ready for Unity 6.3README with complete recording + ffmpeg audio-mux workflow for final videosDocs via chat
