I find a plugin which named AnimToTexture in UE5.1, In short, it ‘s used to make GPU animation. I can correctly show animation of static mesh after look up information on internet. But some small problems happened, that the animaiton has some tiny shake and offset.
This video also shows how to use the plugin, and also has the same problem as me.
The author dont solve it, but he suspect that it’s beacause of texture format uncorrectly.
He used himself own tools for exporting texture. I used the BP_AnimToTexture blueprint which provided by the plugin.
I find there are three textures used by bone animation in the plugin’s example. Position texture and rotation texture are FloatRGBA, but weight texture format is B8G8R8A8. I copyed them，And use BP_AnimToTexture to exporting new textures，but all three textures’ format changed to B8G8R8A8。Did someone know why and how to solve it?

偶然发现UE5上架了新的插件AnimToTexture, 简单来说就是用来做GPU Animation功能的。
到处搜资料和使用方法，终于正确的显示出静态网格动画了。
但是有一个小问题，就是烘焙出的动画，会出现抖动与位移。跟上面视频的问题一模一样(在15:37)。
这位作者貌似也没有解决，他怀疑是纹理格式出问题了。他是用自己写的工具导出纹理的，而我使用插件里的BP_AnimToTexture蓝图导出的。
我发现，插件例子里的骨骼动画所使用的三张贴图，位置与旋转纹理格式是FloatRGBA, 权重纹理格式是B8G8R8A8。 我复制了这三张贴图，用BP_AnimToTexture导出新的纹理后，纹理格式全都变成了B8G8R8A8。
有人知道这是怎么回事吗，我刚入门UE，不知道是不是犯了什么小白错误。）
