Distant Horizons - Support for "Increase quality when zoom in" option

[narnianpony]

I posted this issue in the Distant Horizons discord and looks like shaders need to support this feature.
When using the spyglass there is some flickering with the "Increase Quality when Zoom In" activated

• It works fine with shaders disabled.
• Minecraft 1.20.1
• DistantHorizons-3.2.0-b-1.20.1-fabric-forge
• embeddium-0.3.31+mc1.20.1
• oculus-mc1.20.1-1.8.0
• MakeUp-UltraFast-9.5c

There is not relevant information in the game logs.

Thanks

On what basis do you say this?: "...and looks like shaders need to support this feature."

I can see that it works: the geometry becomes more detailed when zooming in. Shaders don't generate Distant Horizons' geometry. It only draws what Distant Horizons or Minecraft gives it. Have you verified that this doesn't happen with other shaders?

If it works fine without shaders, it could be a bug in Iris or Sodium, which is what communicates with Distant Horizons, not the shaders.

If you have any source indicating otherwise, please point it out here.

I also tested on ComplementaryUnbound_r5.8.1 and had the same problem. Someone else reported the same with Bliss on DH Discord Server (see comments) https://discord.com/channels/881614130614767666/1530645435109343453
