About this mod
Fix for AMD GPU's not rendering local star/sun in the sky
Permissions and credits
This fixes the issue where the sun is not rendering for some AMD GPU users when visiting planets.
Installation:
In your graphic settings ini file (low.ini, medium.ini, high.ini or ultra.ini) in the game folder (if Steam then Steam\steamapps\common\Starfield ) add these lines:
[ViewDistance]
fFarDistance=100000000
PS. Perhaps view distance can be even lower, test it out and see.
Enjoy the sun.
