Hello Boys and girls 
We know there is a “Was recently Rendered” function! But we wan’t something more detailed. Our problem is to calculate the width of an sphere when i zoom out or in because the width is different on the screen then. We tryed it wirh “ConvertWorldLocationToScreenLoation” and it works perfect with the Center of the sphere. If the Center of the sphere is out of the Screen our function works. But we need to add the width of the sphere then. We try the Bound function but this is everytime the same. We need the real width on the screen.
This only works for the center:
