    Engine Plugin
    This product contains a code plugin, complete with pre-built binaries and all its source code that integrates with Unreal Engine, which can be installed to an engine version of your choice then enabled on a per-project basis.

EasySynth is an Unreal Engine plugin for the easy creation of image datasets from a moving camera, requiring no C++ or Blueprint knowledge. It leverages native Unreal Engine components to create compelling machine learning datasets, without relying on 3rd party tools.


The plugin provides a simple interface for semantic labeling of actors present in the scene and works by automatically starting the rendering of a user-defined level sequence, with different camera post-process settings. Outputs that can be created are the following:

  • CSV file with camera poses, including position, rotation, and calibration parameters
  • Color images rendered by default
  • Depth grayscale images
  • Pixel normal images
  • Optical flow images between frames
  • Images with actor' semantic labels
