Development Programming & Scripting C++

        .......
	virtual bool RequiresHitProxyStorage() override { return true; }
        .......

I overrided the RequiresHitProxyStorage method to return true. Then GetHitProxy won’t crash.

But I still get nothing undercursor.



	HHitProxy* HoveredHitProxy = Viewport->GetHitProxy(CachedMouseX, CachedMouseY);

Thanks for sharing that.
For clarity you had to make Engine Source changes to get it to work?
EDIT: Yeah seems like you have to.

So its been a while since I went down this road, it was also back in UE4 probably like 4.19 or so.

If I recall correctly I sort of got something working but I wasn’t able to package because all the core hit proxy stuff was editor code, and you can not package with editor code for a runtime game.

So in my case since I was doing some X ray type stuff and my xray was making certain objects invisible the size of a sphere, I wrote some code to ignore any clicks in that sphere space so I was able to ignore clicks for actors / parts of actors that were not visible but still click on them for parts that were visible.

That said if you won’t to go down this road, looks like there is an archive of that site here.
