RelightKit lets you relight ordinary 2D footage with physically based lights — no 3D scene, no projections.
It works on AI-generated PBR passes: UniVidX extracts Albedo, Normal and Irradiance from your footage, DVD provides temporally stable Depth. Both models run through ComfyUI — the ready-to-use workflow is included, so a working ComfyUI setup is required to generate the passes.

In Nuke, a one-click loader builds the graph with OCIO-aware colorspaces. Roughness, Metallic and Specular are derived automatically from the AOVs. Then just drop lights on your plate: Point, Point (Depth), Directional, Area, HDRI Environment — all shading with a full GGX BRDF per-pixel on the GPU.
