Bring detailed animated smoke to URP scenes with four adjustable presets, volumetric shading, a ready-to-use industrial demo, and editable shader and C# source.Ultra Realistic Smoke URP plays an offline fluid simulation through an editable URP volume shader. Adjust density, color, wind, spread, playback speed and sample counts directly on the included prefabs.The package includes Cinematic Plume, Dense Soot, Soft Steam and Wind Shear. These are four treatments of one shared simulation, with 47 interpolated 3D density frames. The Industrial Study scene provides a configured camera, lighting, cinematic grading and controls for comparing the presets. It uses connected smoke and studio-set prefab instances, with the reusable Industrial Vent prefab nested inside the studio set.The shader integrates extinction through a bounded volume and samples density toward the main directional light for internal shading. Opaque scene depth clips the smoke. Runtime and shader source, offline setup documentation and optional production files are included.Requirements: Unity 6000.0.30f1, URP 17.0.3, Linear color space, a perspective camera, a main directional light and depth available before transparents. URP is a Unity Package Manager dependency. There are no paid asset dependencies, services or runtime AI calls. Blender 3.6 is optional for editing the production source and is not required to use the Unity effect.Limits: this is baked volume playback, not a runtime fluid solver. Scene objects do not redirect the smoke. Wind and spread deform the baked density. Point and spot lights do not illuminate the volume, and the smoke does not cast a projected volumetric shadow on the environment. Intersecting transparent volumes have sorting limitations. High density and low ray sample counts can reveal bands. HDRP, Built-in, mobile, WebGL, XR and orthographic cameras are not supported configurations for this release. Windows desktop / Direct3D 11 is the tested target.Performance depends on screen coverage, resolution, quality and overlapping instances. The demo includes an FPS display and adjustable quality. The source density is sampled at 12 Hz and interpolated each rendered frame; high rendering FPS does not add simulated motion states. The showcase video is recorded from Unity at 60 FPS.Publisher: EstiWebsite: https://www.esti.tr/Support: info@esti.trVFX included: Cinematic Plume, Dense Soot, Soft Steam and Wind Shear — four presets of one shared baked simulation.Package contents: four smoke prefabs, one reusable Industrial Vent prefab, one Industrial Study Set prefab and one demo scene using connected prefab instances.Density textures: 47 R8 Texture3D frames, each 96 x 128 x 96; approximately 52.9 MiB of raw density data plus overhead. Source sampling is 12 Hz, approximately 3.92 seconds per loop at authored speed, with adjacent-frame interpolation and an eight-frame loop crossfade.Additional textures: one 64 x 64 x 64 periodic RGBA noise texture, one studio reflection cubemap at 64 x 64 per face, and one 16 x 16 uniform base-color map.Models: two FBX files containing 51 mesh parts, 39,946 triangles and 63,362 vertices in total. Seven materials with adjustable color, metallic and smoothness settings; the demo environment is not a scanned PBR texture collection.Custom shader: one editable HLSL volumetric smoke shader for URP. Main directional-light density shading and opaque depth intersection. Four runtime C# scripts, custom inspector and optional setup window; runtime/editor assemblies are separated.Quality presets: 64/3, 96/5 and 128/6 view/light samples. Performance varies with resolution, smoke screen coverage and overlapping volumes.Tested: Unity 6000.0.30f1, URP 17.0.3, Windows / Direct3D 11. Linear color space, perspective camera and depth available before transparents are required. New Input System and Play Mode with domain/scene reload disabled were checked.No runtime fluid solving or object-driven smoke collision. No point/spot-light illumination of the volume. No HDRP, Built-in, mobile, WebGL, XR or orthographic camera support claimed.Documentation and optional production source are included. No external font or audio files, paid asset dependencies, services or runtime AI calls are bundled.AI was used during code refactoring and scene preparation.
