Optimised Volumetric Smoke (OVS)
A lightweight, GPU-instanced volumetric smoke system for Unity. Built to stay cheap on the frame budget while looking soft and natural — with ready-made colour presets you can drop straight into a scene.
- GPU-instanced volumetric rendering
- Lightweight & performance-first
- Works in URP & Built-in pipelines
- Multiple colour presets included
- Drop-in prefab, no setup required
Performance: on the developer's RTX 3060 Ti, the Built-in Render Pipeline holds 700–800 FPS with multiple smoke instances on screen at once. The benchmark screenshot reads slightly lower because capturing it pulls focus from Unity, which throttles the frame rate while unfocused. URP naturally runs lower — realistic 3D URP performance depends heavily on your own renderer configuration and optimisations, so these Built-in figures are a best case rather than a guarantee.
