Mesh Baker v3.26.2更新日志
3.26.2 (当前)已发布 2018年12月20日
Version 3.26.2 December 19, 2018
Add Drag & Drop target box when adding objects to be combined.
Fix bug when using TextureBaker, multiple materials and trying to split the result into multiple atlases which did not work.
Fix issue when using Texture Packer, Mesh Baker Fast on Metal platform where atlases would be upside down.
Fix issue where UpdateGameObjects would not work correctly if the material was switched on the source game object.
Move Editor scripts into a folder that is not a subfolder of the Scripts folder. This was necessary so that assembly definition files and the Unity test runner will work in Unity 2018.
Split the MB3_MeshCombinerSimple class into multiple files because it was very large.
Added an example scene and script for switching a material on a source object and updating the combined mesh.
