Instead of hunting through node trees to find the "Sun Intensity" value, artists now have a clean UI in the 3D viewport. Version 1.3 added presets for different planetary conditions—Earth, Mars, and Alien worlds—allowing artists to start with a base and tweak from there. The shadows are too soft or too hard

The standout feature is the inclusion of actual stars and celestial bodies. While most engines focus only on the Sun, PSA 1.3 allows you to manage the Sun, Moon, and Stars as individual physical entities.
