What Can You Automate In Unreal Engine?1:08
What can you automate in Unreal? What is Python API meant for?

Initial Unreal Engine Setup2:21
Unreal Engine settings setup for Python automation. Which toggles to switch and which plugins to enable.
IDE specific setup will be covered in separate tutorials.
Setting Autocompletion in VS Code (Stub file)4:48
How to set up Intellisense autocompletion in Visual Studio Code for Unreal Python API scripting.
Setting Autocompletion in PyCharm (Stub file)5:33
How to add auto generated Unreal Python API stubs to PyCharm and enable autocompletion and error highlighting.
Typing in Python2:28
How to use type hints in Python.
While this lecture does not directly focus on Unreal Engine, it may be helpful to many of you.
In this course, I do my best to keep the code readable and typing is one of my favorite coding practices that boosts readability, limits space for error and is also helpful for generating documentation with tools like Sphinx.

Make your scripts discoverable by Unreal6:25
You will learn how to make your scripts discoverable so they can be imported in Unreal Log or in other scripts you have created just like any Python module you would normally create outside of UE.
Running Scripts From Editor2:06
How to run Python scripts in editor using Output Log window.
Running Scripts With Commandline3:51
Run your Python scripts with command line without even starting Unreal editor interface.
Startup Scripts and init_unreal.py3:11
Create startup scripts that execute as Unreal editor starts. They can be used to initialize tools, register validators and more.

Getting User Selection And Listing Assets11:02
What is a difference between Asset and Actor? How to list them, how to get user selection, how to list all assets from a given directory and more.
Filtering Asset/Actor List With EditorFilterLibrary11:41
There’s no need to write your own utils for filtering assets or actors by class, name, tag or selection. You can use a built in library.
Texture Compression Settings Validator - Accessing Editor Properties17:06
You will learn accessing editor properties, checking if your texture uses optimal compression settings and batch fixing those settings.
If you are interested in Asset Validation, check out Asset Validation section in the course - this topic deserved a separate section!
Importance of PropertyAccessChangeNotifyMode in setting editor properties10:45
Debug, fix and avoid bugs related to setting editor properties not refreshing/recalculating other related properties.
Editing Material Instance Parameters - Material Editing Library10:53
Editing Material Instance parameters with MaterialEditingLibrary.
Find Duplicated Actors On The Level13:00
ImportRules Plugin - Run Custom Post Import Action28:47
Automate post-import actions in Unreal Engine 5 using the Import Rules plugin and Python, defining queries and actions to organize assets by mesh type metadata.
Post Import Actions Using ImportSubsystem17:29
Register and use the Unreal import subsystem post-import callbacks to run actions on asset imports and re-imports, and apply meta tags and import rules to move assets.
Remove Unused Assets19:34
Batch Import FBX Meshes (Asset Import Task)24:50
Batch Import Textures (Automated Asset Import)8:52
Batch import textures in Unreal Engine 5 using Python automation with an automated asset import function, converting Pathlib paths to strings and returning a set of Unreal objects.

Why you need asset validation - Intro to asset validation in Unreal Engine3:21
What is asset validation and how it helps you find issues in you assets even before you submit them to the project.
Naming convention validator15:40
Implement naming convention validator in Python. The validator will detect incorrect name prefixes.
It will expect T_ prefix for Textures, BP_ for Blueprints, M_ for Materials and MI_ for Material Instances.
Square texture validator5:47
Non square textures (ex. 1024px x 512px) are completely justified in some cases like tall grass textures but in majority of applications it's unnecessary and may cause a tiny performance loss.
A simple validator can help you detect those cases with just few clicks.
Power of two texture size validator5:25
Non-power-of-two textures have been not supported by many GPUs for years. They were either causing crashes or required rendering workarounds that lower game performance.
They are considered a bad practice but let's be honest: when working on many files for months, it's easy to export some wrongly sized textures and it would be nice to have a simple tool to help us find and fix such issues.
Triangle count validator10:55
Validate asset triangle count.
Do you have a set limit of triangles for environment, misc or maybe character meshes? Now you can warn user if it is exceeded.

Adding custom menu actions14:05
Menu Entry Icon7:07
Followup to Menu Entries18:32
Menu Entries - Additional Notes0:31
Progress bars for slow tasks2:49
Undo and Redo operations5:48
Introduction to automation testing in Unreal Engine6:17
Explore automated tests in Unreal Engine, including unit, feature, and smoke tests, and learn to use the Python automation test plugin for testing.
Writing your first Python test for Unreal16:01
Appendix: New to automated tests?2:18
Supressing warnings in Python tests.0:43

Remote Control In Unreal - Overview and Quick Setup2:48
Control Unreal Editor behavior via the remote control api and web interface, exposing properties with a remote control preset or calling Python code remotely, for virtual production.
Remote Control Preset and WebApp19:33
Remote Control Preset Controllers12:44
Build remote control presets that automatically apply team colors and driver text via a web interface, using conditional and binding to synchronize car paint and text across assets.
Python and Remote Control API + Testing API with Insomnia15:02
learn to trigger python code in unreal via the remote control api, test with insomnia, and expose unreal classes with decorators to build simple ping calls and return parameters.
Remote Control Python Progress Bar16:53
Direct FBX Mesh Export From Blender To Unreal [Real Life Tool Demo]9:16
Example application of combining our knowledge on Remote Control API and on importing FBX meshes from code.
Treat this video as an inspiration for creating tools that give users smooth experience.
Making sure Remote Control calls work in Unreal 5.5+ with correct Object Path12:38
In Unreal 5.5, names of Python objects changed slightly and your old code may not work.
Watching this tutorial will help you resolve this issue.

Reason behind the change is explained in fix report: https://issues.unrealengine.com/issue/UE-247331

Requirements

Basic understanding of core Unreal Engine features
Experience working with assets in Unreal
Python programming
Understanding of Object Oriented Programming principles

Description

Learn how to automate your Unreal Engine 5 workflow and increase your productivity.

Led by a senior developer with experience in the AAA industry known also as Tech Art Corner, this course will teach you everything you need to know to automate Unreal Engine with Python. You'll learn how to create powerful tools that will perform tedious tasks in the blink of an eye, freeing up your time to focus on more important things.

By automating repetitive tasks, you'll not only save time, but also reduce the risk of human error and increase the overall quality of your work.

Throughout the course, you'll be guided through the setup process, learn basic concepts of automation, and create scripts that operate on both Assets in Content Browser and on Actors on the level.

You will also explore different ways of delivering those scripts to the end user, ensuring that your tools are easy to use and accessible.

By the end of the course, you'll have a foundation in Python scripting and automation techniques.

Whether you're a seasoned Unreal Engine developer or just starting out, this course is an essential tool for anyone looking to streamline their workflow and achieve more in less time.

Who this course is for:

Unreal Engine users who want to optimize their workflow and pipeline
Technical Artists / Game Developers / Pipeline Engineers who want to speed up their workflow
