Just attach to your 3D text and set the properties, works fine for most purposes. Doesn’t account for Non-Mono-spaced font issues.

Feel free to improve upon it, I just needed this for a project and it met my needs and performance metrics.

I hope no one minds if I bump this, but I was wondering if there was a way for the script to reset the wrapPoint when it detects a line break in the string. This script is working great so far, it’s just that every time I line break it still thinks that it’s in the same line as before.

DESIRED EFFECT:  
This is the first sentence.  
This is the second sentence.

CURRENT EFFECT:  
This is the first sentence.  
This is the  
second sentence.

UPDATE: I’ve figured out a way around it! I’ve added an if statement in the script after the hyphen if statement and before the get component part:

```auto
if( message[count] == "`" ){
     currentLength = count - startPoint;
     appendText = message.Substring( startPoint+1 , currentLength-1 ) + "\n" ;      
     finalString += appendText;
     currentWrap = count + wrapPoint;
     startPoint = count;
}

```

Now whenever I put `in the string, it will always line break and reset the count (wrapPoint) to 0. If you have to put` in your sentence, you could replace it with any symbol or letter you don’t really use like ~ or \*. Just make sure it’s ONE symbol, because if you put more than one it the if statement it won’t register.
