How to create rigged 3dModel in Blender and setRotation in irrlicht?

Question

I have edited a rigged human model in blender (to change the axis of rotation of certain joints), to export it to Irrlicht and setRotation on the model's joints.

Irrlicht detects the joints in

node->getJointNode("Stacy_Armature_Bone_013");

but when I try to apply a rotation with

node->getJointNode("Stacy_Armature_Bone_013")->setRotation(core::vector3df(10, 0, 10);

it doesn't move.

Before editing the model, I could change any joint's rotation at will, but now it doesn't work. So I can only suppose the problem is in some setting in Blender.. Any thoughts? Thanks a lot!
