Hello, I am currently trying to expose some of the Omniverse Unreal Engine Connector functions to Blueprints, but I cannot manage to do it. Since I saw that other functions are already exposed to blueprints, why can’t I expose those using the same structure, namely converting the class to a UCLASS…

Which class did you try to convert to UCLASS?

I tried to convert the FOmniverseFacialAnimation to UCLASS, changing the F to an U whenever the class is called

Try this: UCLASS() class OMNIVERSEUSD_API UOmniverseFacialAnimation : public UBlueprintFunctionLibrary { GENERATED_BODY() public: UFUNCTION(BlueprintCallable, Category=“Omniverse Facial”) static bool LoadFacialAnimation(const FString& Path, const FString& Dest, class USkeleton* Skeleton); s…

I’ll try this and I keep you updated, Thanks very much !

So I did everything just like you indicated, and the project compiles nicely, however, I can’t manage to find the function while in the Blueprint Editor, which is a bit weird and indicates that the function hasn’t been detected by UE5. Is there any way I could solve this problem ?

Maybe you can try this in the UE editor: File->New C++ Class->Blueprint Function Library->a new UOmniverseFacialAnimation class. Then copying the detail from old FOmniverseFacialAnimation

After a bit of thinking, that’s something I tried already, and a problem I faced is that when it compiles, it doesn’t recognize the access paths to other modules such as OmniversePxr.h, nor to all the modules called recursively. This means I need to add by hand all paths to the VS Include variable,…

You can move the 2 functions FindUsdSkelAnimation and CreateFacialAnimationSequence to another new class in a cpp, e.g. FOmniverseFacialAnimationHelper. Then you can get rid of OmniversePxr.h in OmniverseFacialAnimation.h.

I’ll file a bug/feature request internally. It’s a good suggestion we should open some utility functions to blueprint, we’ll make it happen in the future release.
