Here's the text version of a 'MAT' I made to restore the default joint parameters to a Door Figure I made. { version { number 4.01 } actor BODY:1 { endPoint 0 0.74 0.25 origin 0 0.74 0 } actor inset:1 { endPoint -0.242499 0.429399 0.020732 origin 0 0.435937 0.020414 } actor frame:1 { endPoint -0.342499 0.429399 0.020732 origin -0.242499 0.429399 0.020732 } actor door1:1 { endPoint -0.204267 0.408456 0.020925 origin 0.204189 0.408456 0.020925 } actor door2:1 { endPoint -0.204267 0.408456 0.020925 origin 0.204189 0.408456 0.020925 } actor door3:1 { endPoint -0.204267 0.408456 0.020925 origin 0.204189 0.408456 0.020925 } actor door4:1 { endPoint -0.204267 0.408456 0.020807 origin 0.204189 0.408456 0.020807 } actor door5:1 { endPoint -0.209289 0.418941 0.020925 origin 0.209211 0.418941 0.020925 } } I've been using these MATs for a while with no problems and they're very useful. As you can see, the Door has a BODY, inset, frame and 5 doors. All you need to do is leave in the End point and Point of origin lines for each body part. Easy. mac
