CryTools are a suite of maxscripts that add functionality to 3ds Max that does not currently exist. Not just basic functionality that 3ds Max is lacking, but also special functionality and tools that help you troubleshoot, create and manage assets for CryENGINE games.
CryTools currently work with versions 8 and 9 of 3ds Max. The installer can install the cryTiff libs, dlls and plugins for versions 6,7, and CS of Photoshop.
