Sun

Create a bright animated photosphere with an HDR palette and moving surface flakes.

Shader menu · FORGE3D/Planets HD/Sun

Sun Red with the original bright photosphere and separate corona

Before · Boost 3.66 on Sun_Red at fixed EV 3.5.

Paths are relative to Assets/FORGE3D/Planets HDRP.

Use Prefabs/Sun_Red.prefab with Sun/Materials/Sun_Red_01.mat on its root. The corona plates have a separate material.

Set fixed Exposure, then lower Boost from 3.66 to 0.55. Look for more separation in the photosphere pattern. The separately assigned corona and atmosphere can still contribute bright light to the image.

Sun Red with a reduced photosphere gain and more visible surface pattern

After · Boost 0.55 with the same fixed Exposure.
