How do I turn on Orbit Shaders once I am in the game?
Open Options, go to Video Settings, and open the Shader Packs menu provided by Iris. Select Orbit Shaders from your list and click Apply to load the lighting effects.
How do I fix low frame rates while using Orbit Shaders?
Open the Shader Pack Settings screen and switch the performance preset from Ultra toward Low. Lower presets scale back demanding lighting and reflection effects so your hardware can maintain smooth frame rates.
Can I use Orbit Shaders together with Sodium?
Yes, Orbit Shaders is built to run directly on Iris and Sodium. Make sure both mods are active on your client so Iris can load the shader pack on top of Sodium's rendering.
Why do reflections on water and smooth blocks cut off when I look down?
Orbit Shaders uses Screen Space Reflections, which can only reflect blocks and skies currently visible inside your camera view. If the object being reflected moves off your screen, its reflection fades out.
How do I get realistic material shine from PBR lighting?
PBR lighting calculates how blocks reflect light based on their physical surface properties. Pairing Orbit Shaders with a PBR-supported resource pack lets smooth, rough, or metallic blocks react differently to light.
Why am I not seeing volumetric god rays in the sky?
Volumetric god rays only appear during clear days when sunlight can scatter through the air. Look toward the sun through tree leaves or gaps in roofs to see distinct beams of light.
How do I get wet puddles to appear on the ground?
Wet puddles form automatically on exposed ground blocks whenever rain falls in your biome. They reflect nearby blocks and the sky while the storm lasts without needing any manual setup.
Why do torches and lanterns have a soft glow around them?
Orbit Shaders applies a bloom effect that creates soft glows around light sources like torches, lanterns, and glowing blocks. If the glow feels too strong for your build, you can adjust bloom in the shader settings.
Do I need to put Orbit Shaders on my multiplayer server?
No, Orbit Shaders only changes visuals on your own screen through Iris and Sodium. You can use it on any multiplayer server from your client without installing anything on the server itself.
What makes corners look shaded and bright daylight less harsh?
Screen Space Ambient Occlusion adds soft contact shadows inside corners and crevices to give builds extra depth. At the same time, ACES tonemapping balances bright daylight and dark nights so neither looks washed out.
