Behavior rendering without Standalone licence 2005-06-24 - By Sascha Robitzki

No, not for Behavior but for rendering. You cannot bring the XSI cloth
to Behavior, also no rigid bodies, springs and other custom operators.
However you can bake the cloth back in XSI and write it onto disk for
rendering. But maybe you need no cloth for the generic crowd characters,
maybe weighted fake cloth will do the job.
