LightSwitch saves complete lighting setups in Blender and switches between them in one click. Each state captures every light’s power, colour and position, the sky, object and collection visibility, chosen cameras and the colour grade, then restores them all at once. Nothing blends and nothing is duplicated: one key light can be bright and warm by day, dim and blue by night. Fifteen restrained cinematic looks, built the way a colourist grades, sit alongside live light controls for solo, power and aiming. It works with Cycles and EEVEE, supports Pro-Lighting: Skies, and keeps tracking everything even when you rename it.
