Vulkan PostFX

Vulkan PostFX — Minecraft 26.2 Pre-Release 2 Compatibility Update

This release updates Vulkan PostFX for Minecraft 26.2 Pre-Release 2 and continues stabilization work for the experimental VPFX Native Runtime.

Highlights

• Added Minecraft 26.2 Pre-Release 2 compatibility.
• Added NR-1F-C.2 user shader RenderPipeline cache dry-run.
• Added pipeline cache diagnostics for user shader native pipeline creation.
• Fixed invalid runtime shader ResourceLocation construction.
• Split vertex and fragment shader runtime locations.
• Improved fallback logging for user shader pipeline creation.
• Resource reload now clears cached user shader pipelines safely.

Native Runtime Status

The VPFX Native Runtime path remains experimental and opt-in.

This release can create and cache a user shader RenderPipeline in dry-run mode, but it still does not execute the user shader draw path.

Current behavior:

• User shader RenderPipeline creation: enabled for dry-run validation
• User shader native draw: disabled
• Actual draw pipeline: built-in passthrough
• External PostChain skip behavior: unchanged
• Native backend default state: disabled

Tested

• ./gradlew clean build
• Client startup
• In-game native runtime execution path
• Built-in passthrough draw
• User shader RenderPipeline creation dry-run
• Resource reload cache invalidation

Notes

This update does not add multi-pass native rendering, custom native targets, scene depth native access, shadow depth native access, or VPFX schema changes.
