This is the puzzle I used.
It allows me to insert text within an area that I have established, the problem is that if I select the ‘fit’ option the text is sometimes cut at the sides,
I wish I could add the ‘new line’ function how can I do that in this puzzle?
Plus how can I do an automatic resize of the text correctly?
Perhaps adding borders between the text and the area to prevent it from being cut off.
the ‘fit’ option scales text so you probably want to use ‘center’. Anyway, if you want to use ‘fit’, you should adjust the UV of the original textures so that the text is not cut.
Multi-line text is not supported unfortunately, so you need to use multiple textures/materials.
