Lighting is one of the most expensive aspects of interactive 3d scenes in regards to performance. Understanding how to bake lighting will not only greatly improve the visual quality of your lit environments but they'll be more performant as well. For this video, we'll be utilizing Blender as our 3d application to bake out lighting using the Cycles render engine. Baking can be a tedious and sometimes confusing process, so we'll go step by step on how to set this up with just a few objects. We'll discuss tips and tricks on how to quickly pack UVs for baking, improve the baked texture quality as well as how to export the final scene as a .glb with baked lighting implemented to be used in BabylonJS.
