My workflow use CAT in XRef Object, but I found that CAT can't use as XRef Object ince max2013?
Like this:
1, make a CAT rig (dragon), save as DragonRig.max
2, reference the DragonRig.max as a Xref Object scene
3, make some animation, save scene as DragonAnimation.max
4, reopen the DragonAnimation.max , you will found out the CAT rig become a mess
I tested in 3dsmax2011 2013 2015, only 2011 doesn't has this problem
I'm having the same problem. It's a really bad bug. I found that bipeds work with this method, but I haven't had a success using CATRIG with XREF.
Make sure you report it though the proper channel. Help > Speak Back > Report a problem, or http://www.autodesk.com/3dsmax-DefectSubmission
This is very silly and is incredible that Autodesk havent gave any answer to this since the time of the post. Im using 3dsmax 2016, simply created a base human rig on cat, saved the file and imported it as an xref object inside a new file, then saved. Then I closed the file and reopen it (the one with the xref object already imported) and CRASH!, that easy is to replicate the problem that I can't believe Autodesk havent noticed it. I really expect to have support on this, Im not creating a new post because the problem is perfectly explained on it by Mantis3D. Thanks
