the-dark-candle

Headlessly run The Dark Candle, capture screenshots or video of the rendering pipeline, and analyse the output. Use this skill whenever the user reports a visual or rendering problem (terrain holes, floating chunks, dark sky, missing LOD, sky/atmosphere/star issues, lighting glitches, "still looks bad", etc.), or attaches a screenshot of an in-game artefact, or asks for a fresh capture after a render-pipeline change.
