To Reproduce Steps to reproduce the behavior:

  1. load a model with the loader plugin with rotation: loader.load({...model, rotation: [0,90,0]})

Expected behavior the model should be rotated as a unit with the same form

@xeolabs looks like the rotation is applied to the objects individually instead of to the model-matrix?
