hi,
here is my setup:
UCLASS(Blueprintable, hidecategories=(Object, Tags, Physics, PhysicsVolume,Input, Actor))
class AMyClass : public AActor
when I open a blueprint, it is showing the categorie. When I select an instance, on the left bottom panel of the editor it is showing the category.
That hide parameter was set after the blueprint was created, I didn’t test yet with a new one. May be a path to check.
Thanks,
