Talk:Animation in Blender

export problem

I have a exporting problem. I have a model with 2 bones. I created vertex groups and assigned them to the specific vertices and then I made an Armature and parented the model and the Armature, then I made 2 Bones with the same names of the vertex groups, when I animate in blender anything looks fine. I export it and the compiler says: "WARNING: too few bones/vert (0) : it has no bones!" and the second Bone gone What gone wrong?
