XON Shader

XON Shader 1.5 — More depth, cleaner POM, balanced light

Bring more detail to your favorite PBR resource packs while keeping XON's warm lighting, clear water and atmospheric style.

New in 1.5

• PBR resource-pack support: Optional LabPBR 1.3 and OldPBR materials, including normal mapping, surface ambient occlusion, height maps and material highlights. Tested with Primes HD Textures 256x.
• Cleaner surface depth: Parallax Occlusion Mapping adds relief to bark, stone joints and other supported textures. Filtered sampling and adaptive tracing reduce the striping and broken edges seen on stepped height maps.
• Natural highlights: GGX sun/moon glints respect skylight and shadows, keeping covered rooms and non-emissive blocks normally shaded.
• Balanced brightness: Lower exposure brings brightness closer to 1.3 while preserving 1.4's warm palette, grading texture, gradients and atmospheric effects.

Also fixes the Advanced Materials loading failure that could cause Iris to disable the entire shader pack, plus incorrect emission and missing-normal handling.

Getting started

Select XON-Shader-v1.5.zip in Iris. With a compatible PBR resource pack active, open Shader Settings → Materials & PBR → Advanced Materials and switch it On. Use LabPBR for Primes HD. Start with 20% Parallax Depth and 64 base steps.

PBR is optional and defaults to Off; Cinematic enables it. Height-map coverage varies by resource pack, so some blocks remain flat. Higher POM quality costs more GPU time.

Validated with 1,680 native shader compile/link configurations and 173 focused material/POM checks. These checks do not guarantee full-game FPS or compatibility with every resource pack and mod combination.
