Features master controllers and advanced deformers that allow for realistic movement without redrawing. Multiplane Environments:
These fixes collectively made Harmony a highly reliable build for production environments, striking a great balance between the ambitious new features of Harmony 20 and the stability required for daily professional use.
Toon Boom Harmony Premium 20.0.3 fits neatly into complex studio pipelines, allowing multi-user collaboration via Harmony Server.
The 20.0.3 update introduced several functional improvements designed to streamline the technical side of production: Hue Interpolation in Color Fades : A new "Hue Interpolation" option was added to the Colour Fade node
Modern animation frequently blends dimensions. Harmony Premium allows artists to import 3D models (in formats like FBX or OBJ) directly into the 2D workspace. This enables artists to animate 2D characters on top of 3D backgrounds or attach 2D elements directly to moving 3D objects, ensuring perfect spatial alignment. Key Features of Version 20.0.3
