Light Map Maker is a power software tool that helps you to create compelling lighting effects. LMM is a independent program. It's not a plug-in. It's a tool for real-time 3D developers (not only game but also web3d, product display, etc.). LMM's main feature is the addition of realistic lighting to real-time 3D scenes. LMM now supports importing/exporting of some popular 3D formats; so it's compatible with most game development software and 3D designer (e.g. 3D Studio Max, Maya, lightwave,etc).
