The modelling of cloud and haze particle formation remains a challenging, but exciting, topic for exoplaneteers to explore. In this talk, I will review the observational evidence for cloud particle coverage in exoplanet atmospheres. I will discuss the different approaches to modelling cloud formation in current research, from idealised 1D equilibrium models, to sophisticated 3D microphysical efforts. I present some recent results coupling our microphysical model to 3D global circulation models (GCMs) of hot Jupiter atmospheres and also lava/magma terrestrial planets. In addition, I will present post-processing/observational comparisons of our model using Monte Carlo radiative transfer. Lastly, I will speculate on the future prospects of observing, and the importance of fundamental physics in a holistic understanding of their formation processes.
