thank you for the tip with "mousepick" works very well, just to tell, I made it so that I click an object first, safe the object I pick in a viriable and compare that variable to the object I actually wanted to move. With this it worked well so far, or ist there anything bad about it?
And one thing still doesn't work, how do I use the mouse pick for my UI?
So far mouse pick didn't detect the UI but the physical object beneath it, or do I need to ad a physical layer to the UI?
