It seems that RenderFromCamera re-uses the lights that were visible from the camera that is currently rendering, even when the cullingResults are set to a different camera’s culling results.
Is there a way to resolve this in HDRP?
Camera Relative Rendering was the culprit.
How did you fix it? Relative rendering can’t be disabled (without hdrp source code changing)
Sorry for delayed reply.
Unfortunately, it seems that the only current way to disable Camera Relative Rendering is to embed the HDRP package and edit the ShaderConfig file, then recompile HDRP’s cginc. It was easy enough, only takes a few moments, but its a silly workaround to have to do. There should be some API for this, and there probably should be a toggle in the UI.
