Unity 序列帧补帧_unity序列帧插

因为最近项目使用序列帧做动画，然后美术提供的图片数量较少图片较大，图集放不下。所以写一小段代码用来生成中间插帧。 效果感觉还可以有种动态模糊的感觉。但是生成时性能堪忧。如果真的要使用的话可以提前在游戏读条的时候生成出来存着。播放序列帧的时候正常播放就行。

逻辑就是根据两张图片的像素颜色做颜色插值，太复杂做法的我也不懂，做到现在这个程度又正好满足我的需求  。          ；）

运行时如果有以下报错，点击对应图片勾选Read/Write Enable。

【UnityException: Texture '1' is not readable, the texture memory can not be accessed from scripts. You can make the texture readable in the Texture Import Settings.】解决方法
