We found out that the V-Ray Hair&Fur integration may crash in 3ds Max 2010 Design. To avoid the crash, you can do the following:
Go to Customize > Custom UI and Defaults Switcher… and select one of the “Max” presets (“MAX.vray”, “Max” etc, not a “DesignVIZ” one) and restart 3ds Max. Hair&Fur should render fine then.
It looks like one of the options in the defaults preset causes the crash, but we haven’t had time to figure out which one yet.
