I have 2 x-tra columns of frames on my toon boom that I accidentley copied …what do I do to get rid of the other column which I dont need .!
I assume you’re talking about the Exposure Sheet view. right click on the header at the top of the column and chose “Delete Element” or some such thing.
Alternatively, you can do the same thing in the Timeline by selecting the element in question, then clicking the little minus sign.
