HDRP Directional light size

Unity Engine

Good day everyone,

I’m trying to create night lighting scene where the moon (directional light in a physically based sky) varies in distance over time (getting larger and smaller). In the editor I can set angular diameter (e.g. 0.5 on average) but I need to be able to modify this value during runtime. I have not been able to find a code attribute that gives me access to this parameter. Anybody have any ideas or workarounds?

HRDP Directional light is depending upon the Angular diameter of the emissive celestial body represented by the light as seen from the camera (in degrees). Used to render the sun/moon disk.
