Contraption Lights (Bi-directional Coloured Dynamic Lights)

Brings the world-to-structure lighting to the LAMB backend, so real world lights can now shine onto your moving contraptions and Sable sub-levels on the lightmap path, not just Veil. Off by default, controlled by two new toggles; LAMB otherwise stays the default and unchanged.

LAMB world-to-structure lighting (off by default):

• enableWorldToSubLevelLambLight - world lights the surface of Sable sub-levels, both dynamic sources (held torches, glowing mobs, dropped glowing items) and static blocks (torches, glowstone, lava). Needs Sable.
• enableWorldToContraptionLambLight - dynamic world lights (held torches, glowing mobs, dropped glowing items) light Create contraptions. Contraptions already pick up static world light from Create, so this adds the moving sources. Needs Create's Flywheel backend on (the default).
• Only lit areas are ever re-worked, and a still build next to a steady light costs nothing per frame, so the cost stays where the action is.

Beta: The contraption path hooks Flywheel's internals and is tuned to the bundled Flywheel version, so treat it as experimental and report anything odd. LAMB itself and everything from earlier releases is unchanged.
