VulkanMod / Distant Horizons Compat

Distant Horizons doesn't draw anything under VulkanMod. It generates LOD data, but nothing shows up. This mod fixes that, and if you also run Beryl, it puts the LODs into Beryl's shader pipeline so the distant terrain matches the world around you.

What it does

With VulkanMod + Distant Horizons:

• LOD terrain renders, including water
• DH's SSAO works
• DH clouds and beacon beams render correctly

With Beryl installed (optional):

• Beryl's sun, ambient and block lighting on LODs, following the time of day
• Beryl's atmospheric fog on LODs
• LOD water uses Beryl's water shading, so the seam at your render distance is softer
• Beryl's water reflects LODs, fading smoothly to the sky at the edge
• DH clouds get Beryl's cloud shading
  This turns on automatically when Beryl is detected and follows Beryl's in-game shader toggle. With Beryl's shaders off, DH looks the way it normally does. If the Beryl integration ever hits an error, it turns itself off for the session.

Tested with my RTX3090 with near instant toggling between shaders on/off. Obviously with everything shader related mileage varies depending on which GPU you have but during normal gameplay the only time I noticed a frame drop was in entity-heavy areas (Modded villages, a few hundred cows, etc.)

Requirements

Client only. It doesn't need to be on servers.

Compatibility Warning

This mod patches all three mods using the exact versions above. A newer Horizons or Beryl version may break it until it's updated. If something stops working after an update, check that your versions match before reporting a bug.

Known limitations

• No shadows on LODs (Beryl's shadow map doesn't reach LOD distances)
• No screen-space reflections on LOD water itself; it reflects the sky instead
