Ok. We can continue from what you did.
So you have a C++ class ‘AMyActor’ with a Struct property of type FMyStruct.
You created a BP from AMyActory called MyBP.
In MyBP, you can see the MyStruct variable and open up the picker. That’s great.
As “MyAssetClass” is not existing, the pciker show you all the classes and didn’t filter anything (strange but that seems to be the default behavior).
Now we want to filter out the picker, so you should set properly the AllowedClasses meta property to filter a subset of the classes. By example, try to filter AMyActor. You should have 1 result, your newly created BP.
In my case, I wasn’t able to get the proper result when setting the AllowedClasses to a existing classes, the picker was empty.
Thanks,
