Making Backgrounds

Hi everyone.

What’s the best way to create backgrounds for animation? Do you use Toon Boom Harmony directly or do them in Photoshop, for example, and import them into Toon Boom?

Thanks.

Whatever you would like to achieve and feel comfortable with.

Example = Everything is drawn directly in Toon Boom:

Example = Most trees and accessories are directly drawn in Toon Boom.
Skyscrapers and cars are imported from Photoshop, BMW-Dixi imported from Cinema 4D.

Good animations of yours.

Thanks NolanScott
