Unreal Engine Path Tracer currently lacks native AOV/render pass support (e.g., Direct Diffuse, Indirect Diffuse, Direct Specular, Indirect Specular, Emissive).
For film, VFX, and fulldome production workflows, these passes are essential for professional compositing and relighting in tools like Nuke or After Effects. At present, achieving this requires modifying Path Tracer shaders in the engine source, which is not practical for long-term pipeline stability.
Is Epic planning to add native Path Tracer AOV support in Movie Render Queue?
If not, could Epic provide an official extensibility framework to output lighting components (direct/indirect diffuse/specular) without engine modification?
