I've developed a scoreboard that consists of several logical parts. Due to the number of animations needed (I already used up all 10 pages) I had to separate it into some logical parts and put it into separate GT title files.

At first I added the logical parts as layers on the main scoreboard title input. But I quickly found out that e.g. the TransitionIn and TransitionOut are only triggered in the main scoreboard and not the parts that are in the layers.

I then decided to create a blank input and add the parts as layers to that, separate from the main scoreboard, put that input (with its layers) permanently on an overlay and then trigger all animations (transition in/out and pages) all from the scoring scripts. This seems to work, most of the times, but not always. For some reason sometimes it does not render anything at all or stops rendering after working for a while. The problem can occur directly after opening opening the preset file but also sometimes after it's been running for a while.

However in the preview thumbnail of the logical parts of the scoreboard I can see them animate. But the blank input (although it's enabled on an overlay) does not render anything out on screen (also not in the preview thumbnail of that blank input). I have to try a combination of reloading the titles, the blank input and taking it off and on the overlay to get it to render again. Usually after that it works for some time (or all the time) but it could also all of a sudden decide to stop working again.

Is this a bug in vMix? Or am I expecting too much here? I need to combine all the scoreboard parts into 1 (or max. 2) overlays otherwise I don't have enough overlays.
