HOW TO INSTALL

 

For Fabric 1.21.1

 

Install Astrocraft

 

Download "astrovenus bridge" and put it in your MODS FOLDER

 

Download "VenusSky -v0.9.1-Sun-Sky-Hotfix" and put it in your "shaderpacks" folder

 

The shader fully simulates earth and its atmosphere. It is dependent on astrocraft for fabric 1.21.1. It was generted with AI, so I recommend turning off shadows and water effects. Its main purpose is to offer realstic skies and effects, like the belt of venus, and also a visible horizon. It is also compatible with distant horizons. The shader will naturally curve your chunks down with the curvature of the rendered planet. 

 

it requires a mod. i uploaded it its called "astrovenusbridge" or something
