In TextAnimator for Unreal you can create custom effects in many different ways.
Feel free to choose the best methods that better fit you! (Here is a list of built in effects instead)
As you'll discover, thanks to custom effects you’re able to create pretty powerful combinations and results. That said (as with anything powerful) it’s up to you to use them wisely! In theory you could create an endlessly reference of animations inside each one, resulting in a stack-overflow or frame drop if you have too many texts/animations on screen for example, so please be careful to not overdo things!
That said… have fun!
