The interplay of galaxy components shapes their evolution and the resulting output energy distribution. By comparison of observations of their integrated light to stellar population synthesis models, valuable information about the galaxy's properties can be inferred. This comparison is complicated by the severe and poorly understood impact of dust absorption and reemission - an issue which will become particularly important in the Webb Era. We investigate the impact of various dust parameter assumptions on model galaxy spectra associated with Binary Population and Spectral Synthesis (BPASS) models. Grids of models will be produced through an investigation of the extent to which dust emission models can be associated with individual galactic stellar populations, using comparisons with archival data. The study then informs a preliminary release of dust absorption and reemission models as part of the BPASS project. Such models will inform and accommodate the wide variety of dust grain size distributions and compositions which are likely to vary between galactic environments.
