Litematica VulkanMod Fix

by Greensurge

Litematica VulkanMod Fix patches a rendering gap so Litematica schematics stay visible when VulkanMod is installed on Fabric.

FabricClient-side onlyMIT License1.21.11

What it does

Without this patch, schematics rendered by Litematica can show up blank and blue when VulkanMod is active, because VulkanMod's shader lookup comes up empty for them. The fix is a small client-side step that runs only when that lookup fails, and it reads the shaders from the jar of the mod that owns them. It requires Litematica and MaLiLib, with VulkanMod as an optional companion, for Minecraft 1.21.11 on Fabric.

Key features

  1. Shader lookup patch

    Redirects VulkanMod's failed shader lookup to the jar of the mod that bundles the shader.

  2. Targeted fallback

    Acts only on the specific lookup that fails, leaving every other rendering path untouched.

  3. Inert without VulkanMod

    Does nothing unless VulkanMod is installed, so it can stay in the mods folder when switching renderers.
