We present, for the first time, three dimensional (3D) adaptive mesh refinement simulations of a GRB jet crossing a pre-SN progenitor (with resolutions comparable to the resolutions of 2D simulations) (Lopez-Camara et al. 2012). The morphology, Lorentz factor, and symmetries, will be discussed in this presentation. Basically the evolution is divided into three main phases: the jet moving inside the progenitor; the jet just about break out of the progenitor; and the phase where the jet has broken out of the star and is now moving through the circumstellar medium. The resolution and 3D effects are also discussed. Still, as with all numerical work, the current investigation lacks in several aspects and needs improvement as well as further investigations.
