Max's Object Properties grayed out problem

has this ever happen to you? just happen to some model from library. they are locked, when right click > properties. everything is grayed out, I can’t check any check box, can’t make it not renderable, can’t box it… i live with this problem for long time. just wonder if anyone has an idea. thx.

several things you can try:

convert your object to editable mesh, editable poly.
export your object as obj, then import it back.
your object can be in a group, locked or otherwise frozen see if you can find anything about that.

thx

yea, that’s how i been fixing them, sometimes works, sometimes doesn’t. most of the time i just ignore the problem. just wondering if i did something wrong causing that and if that’s just happening to me… or would that has to do with some types of expression encoded into it??? i dont know. thanks anyway.
