| Environment | Client |
LambDynamicLights is a client-side Minecraft Java mod that adds dynamic lights on Fabric, Quilt and NeoForge. Any entity holding an item that emits light as a block now emits that light too, so a torch in your hand lights the tunnel around you. The creator pitches it as the most feature-complete and optimized dynamic lighting mod.
What LambDynamicLights lights up
- Items held by any entity, and dropped items that already emit light as a block.
- Burning entities.
- Natural emitters: allays, blazes, fireballs, glow squids, magma cubes and spectral arrows.
- Firefly particles, guardian lasers, and creepers, which light up progressively as they are about to explode.
- Modded items, since item lighting can be customised through resource packs.
Some items, such as torches and soul torches, do not light up in water. Settings let you choose how smoothly the light updates.
