Changelog

v1.8 (Jun 28, 2025)

Renamed EImageRotation to EThextureProcessImageRotation for UE5.6 and later only. This change was made in response to the addition of EImageRotation of the same name to the VirtualProduction engine plugin.

Unreal Engine 5.2 version is now available.
Added DLLEXPORT so that FOnnxTensorInfo can be used from C++ in other modules.
Added conditional compilation to work with the latest API of ONNX Runtime. See Use latest ONNX Runtime for more details.

Added support for Unreal Engine 5.0 official release.
- To bind single-precision float inputs/outputs from Blurprint in UE5, see this page.
- In UE5, OnnxRuntime module has been renamed to OnnxRuntimeNNEngine module to avoid conflicts with the engine module. Please take care when migrating existing projects.
Updated OnnxRuntime module
- Added an option to specify model optimization level.
Updated demo project
- The DNN model for facial tracking was changed to one that uses an attention mechanism in Human pose estimation demo.

Updated OnnxRuntime module
- Added a Blueprint callable function Construct Onnx Tensor Info. Use this function to dynamically specify the shape of input/output tensors.

Updated TextureProcessing module
- Added a component to convert UTexture to float array. (TextureProcessFloatComponent)
- Added functions to create UTexture from arrays of byte or float.
- Fixed a bug that some UTexture cannot be processed by TextureProcessComponent.
  - Now BP_TextureProcessComponent is deprecated. Use TextureProcessComponent instead.
Updated CustomizedOpenCV module
- Removed OpenCV's check function to avoid conflict with UE4's check macro.
Added example projects
- Added an example for depth estimation using a monocular RGB camera.
- Added an example for arbitrary artistic style transfer.
