I’m building a system where I can configure a vehicle in the editor by selecting a specific name from a data table, which in turns automatically loads everything, from skeletal mesh, animation blueprint, chaos wheel classes, textures, custom animations, and more stuff.

I’ve done something similar with a few other systems within my project, including NPCs and an entire toolkit I’m using to construct my levels, and 90 percent of my project is entirely data-driven using CSV’s.

As I’m implementing this method on vehicles, I find that the chaos wheel class variable i created in the struct does not load the class name I specified in the data table, resulting in a blank pull down menu, which I have to manually edit in the data table for the proper wheel class to be assigned from the construction script of my vehicle.

This might turn into a headache later on as I’m gearing up to design and build 50+ vehicle types, each with their own chaos configurations, animBPs etc. so I definitely could use some help getting those wheel variables to load. Anything I might be missing?

Thanks in advance!

The issue happens because Unreal Engine requires the exact _generated class path_ in your CSV, not just the standard asset name. When you import a class reference (like your Chaos Wheel class) via text data, it specifically looks for the `_C` suffix to recognize the compiled class properly.

Here is how to fix the formatting in your CSV so the variables load automatically:

1. In the Content Browser, right-click your Chaos Wheel Blueprint and select Copy Reference.
2. Paste that reference into your CSV file. By default, Unreal copies it like this:  
`Blueprint'/Game/Path/To/BP_MyWheel.BP_MyWheel'`
3. Modify this text to point to the generated class. Change the Blueprint prefix to BlueprintGeneratedClass and append **\_C** right before the final closing quote.
4. The final string in your CSV should look exactly like this:  
`BlueprintGeneratedClass'/Game/Path/To/BP_MyWheel.BP_MyWheel_C'`

Please, try this solution.
