OCA, the Open Cel Animation format is an open format to ease the exchange of traditionnal/frame-by-frame/cel animation between different applications.

It is able to export all animation keyframes from a Krita document, keeping the layer structure, blending modes, and a lot of other information. This OCA format can then be imported in another application like Adobe After Effects or Blender.

The documentation about OCA is available on oca-docs.rainboxlab.org.

This is the OCA exporter for Krita.
