According to the source code, you can run the commandline with -dllerrors and that will open a window with the error. If you do not want to distribute python sources, you can include only the __pycache__ directory with the bytecode. Using Kolmogorov complexity to measure difficulty of problems? 4 Comments. The build procedure will try to automatically discover python installations. Just remove the .so files in Plugins/UnrealEnginePython/Binaries/Linux and pull the latest code. For some reason its not mentioned in the How-to-install tutorial. I've followed the advice regarding missing dependencies from this page, and have gone through all of the likely DLLs that were reported as not found by the Dependencies utility (mostly DirectX/OpenGL related ones), but the build still fails and I'm running out of ideas.

Sometime methods are implemented for automatically getting the right object. If your objective is to script the editor, you can directly jump to, https://github.com/20tab/UnrealEnginePython/tree/master/docs, https://github.com/20tab/UnrealEnginePython/tree/master/examples, The first directory contains the official documentation for specific areas, while the second one is a collection of python scripts doing any sort of 'magic' with your project ;), We are going to create a new Actor based on python (instead of C++ or blueprints), This is the "gentle" approach, using a 'proxy' python class to speak with the UE4 api.
