The nebular phase of a supernova is a phase rich with information on the ejecta
composition and with it, the progenitor system. With many intricate physical
processes playing important roles, making models for the nebular phase is a
complex task which is usually only done in 1D. Recently however, the first late-
time 3D core-collapse models have become available to use as input models for
nebular phase calculations. Using these 3D inputs requires the development of a
3D nebular phase code. In this talk I will both highlight my latest results with
my 3D code ExTraSS (EXplosive TRAnsient Spectral Simulator) as well as outline
how I approached the designing of this code, as the step from 1D to 3D is
computationally challenging for these detailed nebular phase calculations.
