How to set up Python interpreter in Unreal Engine project on Windows

Question

How to enable Python integration in Rider for Unreal Engine projects?

Answer

Follow the steps below to enable Python integration in Rider:

• Enable Python plugin in Unreal Editor
• Install Python Community Edition plugin
• Configure a new interpreter:
  1. Open your python script directory in Rider using File->Open or (if you are bundling your scripts with the UE project) open your project using sln file
  2. Navigate to Settings | Build, Execution, Deployment | Python Interpreter and add a new local interpreter (Add interpreter -> Add local interpreter...)
  3. Create a new virtual environment using an interpreter bundled with UE as base interpreter (here's an example of the Base interpreter path:{path_to_UE}\Engine\Binaries\ThirdParty\Python3\Win64\python.exe)
• Add the PythonStub to the interpreter paths:
  1. Open Settings | Build, Execution, Deployment | Python Interpreter, use the Python Interpreter dropdown and pick "Show All":
  2. Select the interpreter, click the Show Interpreter Paths button :
  3. Add a new path pointing to PythonStub directory:
     • The PyhonStub directory is located under PROJECTDIR/Intermediate/PythonStub. In case it is missing, see the Setting up Autocomplete for Editor Python Scripting page for instructions to generate it.
• Use Help -> Edit Custom Properties action, add a line idea.max.intellisense.filesize = 25000 and restart the IDE
• Rider should be able to resolve UE symbols and suggest completion shortly after opening a Python script after the restart
