I need to colour my pencil animation and to composite it with a background. I tried to do it in Toon Boom Animate Pro 2, but I can't find there any layer types like "Multiply" in Photoshop to make the background visible. So if I import the pencil drawings without vectorisation, they appear with a white background, and I can't paint them(because of some type of frame), and if the vectorisation is done, I get rough, lacerated lines.
Can I solve this problem in Toon Boom? If not, what software is usually used for colouring and compositing of pencil animation?
You might have to go back and ink over your penciled linework. Toonboom has an automated thing that will convert your inked line work to vector, similar to the "trace bitmap" function in Flash. I'm not sure of specifically how to do it though.
Other than that, you may just have to color your frames in photoshop, cut the white backgrounds out and upload them into toonboom as a png sequence (if that's even possible).
I see, thanks.
