Oh ! Currently, both are set to 'true'.
If Ignore Time Scale is false, but Remember Read Position is true...
-Text readout pauses with editor pause.
If Ignore Time Scale is true, but Remember Read Position is false...
-Similar behaviour to both being true occurs
-All sounds play rapidly when catching up to current readout position
If Ignore Time Scale and Remember Read Position are false...
-Text readout pauses with editor pause.
When toggling them during play mode...
-works as described for each situation
-when Ignore Time Scale is toggled, the sounds from readout will re-play rapidly to catch up with current readout position, but continue from then as described for situation
So it looks like it's mostly a quirk of sorts, from Ignore Time Scale. Ideally, I think it should pause readout (as when Ignore Time Scale is false) when it's an editor pause, but regard to the Time Scale reference otherwise. As it's not a major bug, it's low priority and entirely optional.
However, another quirk I've noticed is when pausing, switching tasks, then returning, the text renderer fails for a frame, giving a null material. This appearance is kept for the duration of the pause when Ignore Time Scale is true. When switching back and forth again, the material is restored as if unpaused. No settings or data are lost during this, so it's also low priority imo.
Thank you ! I'll consider this 'solved' but also sort of as a bug report ? Good luck ! Thanks for all your help. <3
