: A new option called "Automatically Filter Attributes" was introduced to the Stack, Grid, and Slider wizards for creating master controllers. When enabled, this feature will automatically omit attributes that do not change over time within the source frame range, preventing unnecessary data from being added to the Master Controller and keeping rigs clean and efficient.
: Added to the Colour Fade node, allowing for Linear, Circular Shortest, Clockwise, or Counterclockwise transitions when using HSL or HSV color spaces.
Because Harmony is the global studio standard, assets created in this build are highly portable and easily handed off to external partners or post-production houses. Toon Boom Harmony Premium 20.0.3 Build 16743-Ac...
Optimized vector engine performance ensuring smoother brush strokes and zero input lag when using high-end Wacom or Huion drawing tablets.
: Support for the Weighted-Deform Node for smooth texture deformation.
Harmony Premium allows production teams to import 3D models (in formats like FBX, OBJ, or Alembic) directly into the 2D workspace. Artists can position, rotate, and animate these 3D objects within the same camera space as their 2D assets. This feature is heavily utilized in modern anime and action series for complex vehicles, backgrounds, or crowd props. Technical Requirements and Performance To run Toon Boom Harmony Premium 20
