LayaAir 3.2.8 Engine Library

更多版本日志以及IDE的下载，请前往LayaAir官网：https://layaair.com/#/engineDownload

BUG Fixes

1. Fixed a bug where destroying a Spine object did not release video memory, causing VRAM accumulation.
2. Fixed a bug causing animation memory overflow.
3. Fixed a bug where after setting the 2D rigid body angular velocity or setting the rigid body gravity scale to 0, the rigid body would still fall and rotate.
4. Fixed a bug on Windows where button text did not scale when the window was enlarged.
5. Fixed a bug where enabling fast rendering mode in IDE preview for Spine caused an error.

New Features

1. Added: Text/Label now has a Single Character Rendering property. When enabled, characters with the same glyph and font size will share a single global cache, useful for dynamic text. This avoids memory and performance overhead caused by generating a large number of text atlases when text content is frequently updated.
2. Added: FBX model file import option now includes an Add Root Node property, which is enabled by default. Previously, an empty node was automatically added as the root when importing models. Users can uncheck this option to avoid generating an extra root node.
