Just in case someone's already heavily invested time & integration methods with ICE for their project, or interested in ICE_CC's internal script name spaces here's a link: http://www.icecreaturecontrol.com/docs/html/namespaces.html May come in handy for those of us whom have already deeply integrated ICE into their project but not quite ready to strip it all out and start over. I've noticed over time that every Unity update requires namespace references within ICE to be updated when Unity yields those annoying Null Reference Exceptions & GUI-ID conflicts. Pit's ICE_CC was so ambitious and ahead of its time it may very well take years before another developer can eclipse all of its built-in features and combine it with an easy on the eyes UI/UX. The closest comparable competition to ICE (even in its current glitchy status) on the Asset Store requires the combination of multiple plug-ins. In other words, back to prehistoric NPC workflows until Machine Learning NPCs become useable.
