Vulkan-Create Compat

VulkanMod / Create Fly Compat

Fixes the black-screen conflict between **VulkanMod** and **Create Fly** by
disabling Flywheel’s OpenGL-based GPU-instancing renderer when VulkanMod
has replaced Minecraft’s rendering backend, and patching a hard-coded
OpenGL cast in Create Fly’s resource-reload code that crashes under any
non-OpenGL backend.

This is an unofficial, third-party compatibility patch. It is **not**
affiliated with or endorsed by the VulkanMod or Create Fly teams.

What it actually does

Create Fly bundles its own copy of Flywheel, Create’s GPU-instancing
render engine, which talks to the GPU with raw OpenGL calls. VulkanMod
replaces Minecraft’s OpenGL backend with Vulkan, but keeps a partial
OpenGL compatibility shim alive for other mods — enough to fool
Flywheel’s “is a real OpenGL context available” check into saying yes,
even though it isn’t backed by a complete implementation. That produces
a black screen on startup.

This mod:
– Forces Flywheel’s `instancing`/`indirect` GPU backends off when
  VulkanMod is detected, so Create falls back to its already-supported
  non-instanced rendering path (the same fallback it uses when a shader
  pack like Iris is active).
– Skips a resource-reload step (blue-noise texture setup) that
  unconditionally hard-casts to OpenGL-specific classes regardless of
  which backend is active, which otherwise crashes every resource
  reload under VulkanMod.

What you gain / what you trade off

– **Fixes:** the black screen; Create Fly loads and plays normally
  alongside VulkanMod.
– **Trade-off:** Create’s kinetic blocks and contraptions render without
  Flywheel’s GPU instancing under VulkanMod — visually and
  performance-wise closer to running Create with a shader pack enabled
  than stock Create Fly. This is a correctness fix, not a performance
  optimization.

## Requirements

– Minecraft 26.1.2
– Fabric Loader
– Java 25
– [VulkanMod](https://modrinth.com/mod/vulkanmod) 0.6.8+26.1.2
– [Create Fly](https://modrinth.com/mod/create-fly) 26.1.2-6.0.9-4

Built and tested against the exact versions above. Create Fly is under
active development without version tags, so its internals can shift
between builds — if you’re on a different Create Fly build and see the
original black screen return, please open an issue with your
`latest.log`

Installation

Drop the jar in your `mods` folder alongside VulkanMod and Create Fly.
No configuration needed.
