Light-Lab Engine

Light-Lab Engine is a client-side API library for Minecraft Forge 1.20.1 that allows mod developers to create and render real-time volumetric spotlights with advanced lighting effects.

This library provides a high-performance rendering pipeline capable of displaying dynamic spotlight beams, lens flares, projected textures (gobos), and automatic beam collision with the Minecraft world.

This is an API/Library mod. It does not add gameplay content by itself and is intended to be used as a dependency for other mods.
