Unreal Engine Tool: Project Optimise
I made a tool to help you find potential problems and optimisations in your Unreal Engine 5 projects (currently works with UE5.3, 5.4, 5.5). It’s built using Unreal Editor Utility Widgets, so it’s lightweight, easy to set up and use.

It has three main areas of functionality.
Optimisations:
- Search for 19 different types of optimisations
- Spread across 8 asset types
Bugs:
- Search for 10 different types of bugs
- Spread across 7 asset types
Naming Checks:
- Check for assets not using consistent naming conventions
- Define the prefixes you prefer to use in your own projects

Below you can see it in action - I’m searching and generating a list of any Static Meshes in my project that have no LODs (you can see that it finds 59).
NOTE: The tool doesn’t make changes to your project; it only reads your assets to generate logs of potential issues that you could look into.
I thought this was important because projects are highly contextual. What’s correct for one project may not apply to another. For example, a static mesh without collision might be an intentional design choice rather than a bug.

Why This Tool Exists
I have been making games in the Unreal Engine for over 10 years now and I’ve seen how easily small issues can creep into your project without you ever realising. While these problems might seem minor on their own, when they accumulate, they can harm the player’s experience just as much as a major bug could. Think of it as death by 1000 cuts (bugs).
For instance, a sound cue missing its Sound Class could make it unaffected by volume settings, or a static mesh used for a pickup might have no collision, causing it to fall through the floor when dropped.
In much the same way, as your game grows it is easy for small optimisation opportunities to be missed and build up to create a larger impact on your games framerate. This can be for many reasons (all of which I’ve done): rushed development, change in design, lack of optimisation knowledge at that time, and simply human error.
And so that is why this tool exists. I use it in my own projects to help me weed out issues and keep my projects as solid as possible.
I hope you find the tool useful, let me know if you have any suggestions to make it better!
