I have seen that the Collada exporter uses a flag called
Looking at the source file, it seems that this option allows to export additional information in the Collada file :
connectto say if the bone is connected to its parent
tip_zto tell the length of the leaf bones
Without these values, the information is lost as Collada encodes the armature differently.
But where and how
use_blender_profile can be set ?
Am I right about the exporter behavior ?
