1. I created 4 text events, each one dragged in individually from the Media Generator tab,
2. I changed the writing of the text of each, First, Second, Third & Forth but left the text font at the default Verdana.
3. I changed the text font of the First to a random font, Vivian.
4. I clicked the 'copy attribute option' & got this msg

Weirdly while writing this comment I clicked back to Vegas, didn't change anything & clicked the 'copy attribute option' again and it worked 🤷‍♂️, I need to do this a few times to understand what I did & why it didn't then did work.

-----------

I recreated this from a fresh project about 10 times with different fonts but only managed to make it show that msg once, the rest of the time it worked correctly changing the other events, 🤷‍♂️

This is the only time it showed that msg,

@iEmby I noticed you have different fonts on the same text event, so I tried that & get that msg every time. but I don't think I was changing just a single word in my other tests n the comment above, I was changing the whole word

@iEmby Here's another version,

1. 2 text events, I change the font of the word but not the single space that's at the end, the error msg shows.
2. Same 2 text events but this time I highlight & change the word + the single space at the end, this time it worked.

I'm guessing this has something to do with having different fonts on the same text event similar to my vid above.

------------------------

When i use the copy attribute option on single track with text & titles which i created new. it works well

Why this worked at first but didn't when 'when i move some of text event to new track ' I don't know.

I can reproduce this problem by changing different fonts.

By the way, I wrote a script earlier which did something similar to this button in T&T. Just tested, it doesn't have the issues mentioned in this thread, but for fonts, it can only convert a single font.

If need be, I provide the code for the script:

using System.Collections;

@iEmby This behavior is to be expected, the system cannot know where to copy which font on which piece of destination text if more than one variant is to be copied of the same attribute type (such as 2 different fonts).

2 different font sizes does not give an exception, but does not work either...

What should be changed by the developers @VEGASDerek is to catch and return a proper and user friendly exception message such as 'copy attribute option not allowed on multiple variants of the same attribute' or something more meaningful.

@bitman @zzzzzz9125 @Former user

thanks all for your response on my thread.

yeah I think you guys figure this out.

yes I need to use different fonts in one text event.

so here is the problem.

I hope they can fix it with some update like asking user to keep one font or before applying attributes ask user to which they want to keep.

or they can ask for properties which user want to paste as attributes. In my case i dont want to change fonts just position and size. so may be @VEGASDerek and team can make it possible in next updates same like 'Selective Paste Attributes' for effects and others.
