You can have use the same overlay multiple times. Add them on your background and at the same time add the size, position, zone and layer.
Ex:
BACKGROUND - DAY with OVERLAY to S X Y in Z at L with OVERLAY to S X Y in Z at L
S = size X = X axis Y = Y axis Z = zone L = layer
Both overlays will be the same but you can choose to put them in a different position or have it at a different size. The layer helps the overlapping issue. Any overlay you want to be all the way at the top has to be the higher number. For example if I want a teddy bear overlay on top of a bed overlay, I would put the bed at layer 0 and the teddy bear at layer 1.
Here’s a guide on layers:
Now even though you can use one overlay multiple times by adding them onto the background, you cannot animate. As in you can’t shift them, scale them, change their opacity, etc.
You need to change the display name to your answer.
Ex:
input What’s Your First Name?|What’s Your First Name?|Done(NAME)
Then in character settings you would change the character’a display name to: NAME
That should make the speechbubble name whatever name the reader typed in.
