Blend up to 32 animated metaballs with depth-correct URP raymarching, three procedural surface styles, source code, a reusable prefab and polished demo.Metaflux Metaball Particles is a source-included, real-time metaball volume for Unity 6 and the Universal Render Pipeline. Place the reusable prefab, animate its nodes and shape smooth organic forms without textures, Shader Graph or compute shaders.The original HLSL shader raymarches inside a tightly bounded proxy, intersects scene depth and writes correct depth for convincing integration with opaque geometry. Runtime data is uploaded through a MaterialPropertyBlock, allowing multiple volumes to share one material without creating material instances.Three art-directed procedural looks are included:- Aqua Glass: deep translucent-looking cyan gel with soft edge light- Magma Veins: dark crust crossed by animated emissive lava bands- Polar Chrome: cool metallic reflections with cyan and warm studio accentsOpen the prefab-backed demo scene to inspect the complete setup. The showcase cycles automatically, or you can use A / D, the arrow keys, or 1 / 2 / 3 to change styles. The editor builder can deterministically recreate the demo and both supplied prefabs remain fully editable.All runtime scripts, shader code, materials, URP settings and tests are included. The demo's minimal TextMesh Pro/Liberation Sans resources are contained inside the product root with their complete notices and licenses.- Suggested category: VFX / Shaders- Validated Unity version: 6000.0.30f1- Render pipeline: Universal Render Pipeline 17.x- Graphics requirement: Shader Model 4.5 capable hardware- Metaball nodes: up to 32 per volume- Raymarch budget: up to 112 iterations- Lighting: URP main light, main-light shadows and up to 4 additional lights- Surface styles: 3 (Aqua Glass, Magma Veins, Polar Chrome)- Reusable prefabs: 2 (system prefab and complete demo setup)- Demo scenes: 1- Original runtime C# scripts: 3- Original editor C# scripts: 2- Original custom shaders: 1- Materials: 3- EditMode tests: 4- External package dependencies: Universal Render Pipeline, Unity UI and TextMesh Pro supplied by Unity- Demo media: six 2560x1440 screenshots and one 30-second 2560x1440, 60 fps, H.264 video in the matching media folderAI was used during code refactoring and scene preparation.
