A high-performance compute shader based path tracer for Unity3D that works without RT cores, using compressed wide BVH for software ray tracing. It provides interactive/realtime path tracing with Disney BSDF materials, ReSTIR GI, denoising, and supports Built-in, HDRP, and URP pipelines.

Use cases

• add realtime path tracing to a unity game
• render global illumination without an RTX gpu
• generate panoramas with path tracing in unity
• render offline caustics with photon mapping
• test path tracing on integrated graphics
• add ray traced lighting to HDRP or URP project

When to choose

• you want path tracing in Unity on any GPU vendor including integrated graphics
• you need interactive global illumination with runtime object and material changes
• you want both realtime (ASVGF) and offline (OIDN) denoising options

When to avoid

• you need a production-ready, officially supported renderer for a shipped commercial title
• you are not using Unity3D
• you need full multiscatter fog or caustics in realtime
