What configuration overwrites to another?
if an object is configurated as collisionable into xpacx .
Into Objects Properties we change that setting but:
What is the priority?
Xpack or Objects Propeties into BTB?
The property in XPack is only related to "default" property object when you plant it in your model. Of course you may want change this afterwards. The object property exported when you click in "Export" is the same one that appears in BTB project, not the property "default" in Xpack. Of course, both propertys will be the same in case of you don't perform any change on properties dialog after its insertion.
