Copy the rotation, translation, or scale of one bone to another. This is perfect for complex mechanical rigs or secondary animations like hair and clothing.

Spine 3.8 introduced several "quality of life" features that defined high-end 2D animation for years: Spine 3.8.99

To ensure smooth performance, the following system requirements are recommended: Copy the rotation, translation, or scale of one

By the third day, small impossible things began to happen when she glanced upward. A creak of building timber in the flat above resolved into a scale—E minor—then a melody that fit the cracked plaster like stitches.

On Windows, some users have experienced immediate crashes. This is often because the Spine launcher itself is outdated. Your Spine 3.8.99 may be old; the launcher version might be as old as 4.2.06, while the current launcher version is 4.2.19. The solution is to download the latest Spine installer from your license page and reinstall; this updates the launcher and can resolve the crashes.

The most critical reason to use this version is for the 3.8 runtime compatibility. Skeleton data exported using Spine Editor 3.8.99 can be used with the 3.8 Spine Runtimes (the code libraries that play the animations in your game engine). This is fully compatible with earlier 3.8 exports, such as those from version 3.8.85. However, a mismatch occurs if you use the editor with an incompatible runtime: using editor 3.8.99 with a runtime designed for 3.8.85 may cause errors or crashes.

To get the most out of Spine 3.8.99, a structured pipeline from concept art to game engine integration is required.
