SpineViewer

An offline Spine skeletal animation preview plugin for Eagle, supporting Spine 3.4, 3.5, 3.6, 3.7, 3.8, 4.0, 4.1, 4.2, and 4.3.
This package is a universal build for Windows and macOS, compatible with both Windows x64 and macOS Apple Silicon.

Features & Usage:

1. Import a matching set of skeleton files (.skel / .skel.bytes / Spine .json), atlas files (.atlas / .atlas.txt), and their corresponding textures into Eagle. It is recommended to place them in the same Eagle folder while preserving the filename pairing.

2. Open a skeleton or atlas file to preview. Regular images still use Eagle's native preview.
3. Supports animation and skin switching, play/pause (Space), looping, playback speed, timeline scrubbing, zoom-to-fit, background toggle, and premultiplied alpha (PMA) toggle.
The interface supports Simplified Chinese, Traditional Chinese, English, 日本語, 한국어, Русский, Español, and Deutsch, and automatically switches to match Eagle's interface language.
