How can I see and / or lengthen the lifetime of a sprite? What determines its lifetime, where is it shown?
I add it at the very beginning of the timeline, but it only lives up to the first keyframe in other sprites. What the hell? What does the keyframes of other sprites have to do with it? Why does the sprite that I added at the very beginning disappear, although I did not set it to disappear anywhere? I need it until the end of the animation.
Why does the object disappear when passing through the key-frames of objects that have nothing to do with this current sprite?
