For those of you guys that are having issues when switching poses and getting permament black screen. I have tried to troubleshoot this, I can't reproduce it on a clean VAM, everything works, no permament fadeout. My guess is the problem is on your side, probably bloated poorly performing vam that hiccups and skips the un-fade trigger. Because there is nothing else there, really. You push the button, it triggers fade animation (fade out trigger at the start, fade in at the end), and also fires a delay trigger that triggers all the transitions when your screen is black. But since there are so many triggers running, poorly performing vam install sometimes skips some triggers. This can also be tied to how good your processing hardware is, obviously.
But on my end it even works on my "main" VAM (bloated). So I implemented a safeguard trigger that is always fired and will never let the scene stay permamently in fadeout, no matter if your VAM couldn't fire the intended trigger or not. This won't affect the scene in the slightest and I think is a neat way to address it.
If you had this issue before, please tell me if it's gone now!
