To help tap this information we have undertaken 2D polarized radiative transfer calculations to map out the possible landscape of type II SN continuum polarization (Pcont) from 20 to 300d after explosion. Our simulations are based on crafted 2D, axisymmetric ejecta constructed from 1D nonlocal thermodynamic equilibrium time-dependent radiative transfer calculations for a red-supergiant star explosion.
