Quaternion must have norm == 1.0 (DOCS UNCLEAR)

[FlashlightET]

I am simply trying to rotate a mesh. Why are the docs so unclear??

what ive tried:

pyrender.Node(mesh=mesh, rotation=(1.0, 1.0, 1.0 ,1.0))

pyrender.Node(mesh=mesh, rotation=[1.0, 1.0, 1.0 ,1.0])

pyrender.Node(mesh=mesh, rotation=np.array([1.0, 1.0, 1.0 ,1.0]))

but np.array([0.0, 0.0, 0.0, 1.0]) works
