# Iris Veil Compat
\nAllow mods using the Veil rendering engine (such as **Create: Aeronautics**) to render correctly when using Iris shaderpacks.<\/p>\n
# Principle
\nVeil is an advanced rendering SDK for Minecraft mods \u2014 it provides a shader infrastructure that other mods can build on. The most prominent consumer is Create: Aeronautics, which uses Veil for its airplane wings, glass panels, contrails, and other visual effects.<\/p>\n
The problem: when you enable a shaderpack via Iris, Veil-rendered visuals bypass the shaderpack’s pipeline entirely, causing them to appear broken or missing.<\/p>\n
This mod automatically merges Veil shader code into the shaderpack’s gbuffer programs at runtime, so Veil-based visuals (like Aeronautics planes) integrate seamlessly with your shaderpack.<\/p>\n
# Implementation details<\/p>\n
This mod intercepts Veil’s shader compilation via mixins, capturing and caching the processed shader source. At render time, it injects Veil shader logic into the shaderpack’s gbuffer vertex\/fragment programs using AST-level patching (powered by glsl-transformer), and creates an Iris `ShaderInstance` to replace the original Veil shader.<\/p>\n
The cache is automatically invalidated when you switch or reload shaderpacks \u2014 no restart needed.<\/p>\n
# Compatibility
\n– **Iris** 1.8.1+ (required)
\n– **Sodium**
\n– **Veil** 4.0.0+
\n– Tested with **Create: Aeronautics** (Spring, Laser) and **Sable**<\/p>\n
