So every time my spacecraft gets hit by an asteroid, it gives some visual feedback by changing transparency. However there are times when my spacecraft isn't touching the asteroid visually but it still changes transparency meaning the image is bigger than it seems.
I've seen other discussions where danpost suggests using his scenario that got rid of the excess background, but it seems it's outdated and no longer works, is there an updated version? Or is there any other way to remove the excess background?
