today i copy/paste scene elements to a pivot for better overview.
but if my pickup truck belongs a pivot the "nav obstacle" flag is ignored,
means there is no space in nav mesh.
2. if u click a object in 3d view the top level pivot with all sub object are selected, that is unwanted.
3. if monster belongs a pivot they run to player but not attack. they can't calculate distance or so.
4. the thing with a pivot group inherited the light shadow cast.
ohh, please please please make a context menu over selected items "set group .."
then a list appear with group names. in list u can add/remove group names.
beside group name the sub object count stay in brackets.
removing a group, content will goto root.
all groups just listed in treeview.
