The BP_Commentary_Box from the demo Blueprint in the Epic Games contains errors.
Hello Loux xavier,
The way to fix this error is to drag off of the execution pin of the Add Text Render Component and add a new Set Text node. Then, drag the string that was attached to the initial Set Text node into the new node, and it will convert from string to text. Then, plug the Return Value of the Add Text Render Component into the Target pin of the Set Text node. The reason that this was coming up on an error is because the node was out of date, and that particular node now takes a Text value as input instead of a string. Hope that helps.
Thank you ^^ It was just to report
