Okay, at least once, there was I time I could draw a background in Toon Boom, export it for Photoshop, and paint over it to export as a PNG for Toon Boom. Attached is a little proof of it.
Am I missing something, or is there no way to export a single drawing layer anymore? I mean, supposing I wanted a giant, scrolling background? Drawing it beforehand, with my animation, is a luxury I don’t want to lose.
