KKReshade

A Reshade addon for facilitating interaction between Reshade and KK/KKS/HS2/AI.

Note

This addon currently only activates when running in Studio mode (CharaStudio.exe or StudioNEOV2.exe).

Installation

Build the solution and copy KKReshade.addon to Reshade's addon directory (usually next to the game executable or dxgi.dll).

Features

Real-time Screenshot Access

This addon captures the final rendered frame (after all Reshade effects are applied) and makes it available via Shared Memory. This allows external applications (like a Unity plugin) to read the frame data.

• Shared Memory Name: KKReshade_Screenshot_SHM
• Data Structure:

  #pragma pack(push, 1)
  struct ScreenshotMemory
  {
      uint32_t width;
      uint32_t height;
      uint32_t channels; // Always 4 (RGBA)
      uint8_t imageBytes[]; // Pixel data (Row-major)
  };
  #pragma pack(pop)

Capture Control

To minimize performance impact, the capture process can be toggled on/off dynamically.

• Control Shared Memory: KKReshade_Screenshot_Control_SHM
• Usage: Write a single boolean byte (1 or 0) to this shared memory segment.
  • true (1): Enable capture (updates KKReshade_Screenshot_SHM every frame).
  • false (0): Disable capture (stops updating shared memory).

Note

This feature is only supported by newer versions of the VideoExport plugin. It is fully backwards compatible: if no control signal is present, capture defaults to enabled.

Technical Details

• Format Handling: Handles backbuffer formats R8G8B8A8_UNORM and R8G8B8A8_UNORM_SRGB used by KK/KKS/HS2/AI.
• Resolution Support: Supports up to 8K resolution (7680x4320).

Building

Open KKReshade.sln in Visual Studio 2022 and build the Release configuration.
