hey , thank you very much for your help! I really appreciate it that you tried to help me!
After endless digging through the engine code I think I kinda solved the problem and apparently you’re right; the problem is indeed that the Sprite I’m using has no BodySetup - so one has to turn on 3D Collision for the Sprite one is using in the Editor. OMG. This issue has really got me busy for days. I really have to say that Unreal really sucks regarding documentation and being buggy! Thanks again for the help though!
But it quite clearly is a bug, isn’t it? I mean, you should be able to change transforms even though the Sprite has no collision enabled, right?
