Changes

Vulkan PostFX 1.15.1

This update introduces the first-generation VPFX in-game UI.

The old pack selection experience has been replaced with a cleaner Reese-style VPFX settings screen. This makes pack switching, backend inspection, reload testing, and debugging much easier while reducing the amount of screen space taken by large vanilla-style buttons.

Added

  • Added the first-generation VPFX settings UI.

  • Added a new Reese-style VPFX pack/settings screen.

  • Added tabbed VPFX pages:

    • Packs
    • General
    • Backend
    • Debug
    • Developer
    • About

  • Added a compact VPFX pack browser.

  • Added pack status display, including source, backend hint, pass count, and target count.

  • Added backend status display for the active runtime backend.

  • Added native direct / PostChain runtime state visibility in the UI.

  • Added fallback reason and failed effect information to the UI state snapshot.

  • Added VpfxUiState for UI-facing runtime snapshots.

  • Added VpfxUiService as a UI facade for reading VPFX state and submitting UI requests.

  • Added first-pass tooltip support for UI rows and buttons.

  • Added compact action buttons for Apply, Reload, and Done.

  • Added paged pack listing for cleaner navigation when multiple VPFX packs are available.

  • Added a 26.2 snapshot-compatible screen bridge for opening and closing VPFX screens more safely across unstable mappings.

Improved

  • Improved the VPFX pack selection workflow.
  • Improved visibility of the currently active VPFX pack.
  • Improved visibility of the active backend.
  • Improved development ergonomics when testing multiple VPFX packs.
  • Improved UI readability by replacing the old large-button layout with a cleaner custom layout.
  • Improved diagnostics visibility for broken or fallbacking VPFX packs.
  • Improved separation between UI code and runtime code.

Changed

  • F7 now opens the new VPFX settings / pack browser experience.
  • Pack selection is now handled through the new VPFX UI.
  • Runtime and pack information is now collected through a UI snapshot layer before being rendered.
  • VPFX settings are now organized into category pages instead of a flat button list.

Notes

This is the first generation of the VPFX UI.

The goal of this version is to establish a cleaner in-game control surface for VPFX development and testing. The UI is not final yet, and more polish will be added in later versions.

Future UI work may include:

  • more complete tooltips
  • better pack detail panels
  • clearer native compatibility diagnostics
  • more developer/debug controls
  • visual polish
  • improved responsive layout behavior
  • better localization coverage

Vulkan PostFX is still experimental. The native runtime, VPFX pack format, and UI may continue to change as the project evolves.
