图片资源冗余：

UPR unity的性能优化工具检查资源
在这里插入图片描述

1.检查纹理读/写标记
开启纹理资源的读/写标志会导致双倍的内存占用
检查Inspector -> Advanced -> Read/Write Enabled选项

2.检查纹理资源alpha通道
如果纹理的alpha通道全部为0，或者全部为255，可以认为其中不包含有效信息，此时应禁用’Alpha源’标志，否则会浪费这部分的内存。
检查Inspector -> Alpha Source选项

3.检查纯色纹理
纯色纹理的使用可能可以由一些设置来代替。由于某些情况下纯色纹理是必不可少的，此警告仅会在所使用的纹理较大(大于设定值, 默认为16x16)时才会触发。
Custom Parameters: heightThreshold : 16widthThreshold : 16

4.检查重复纹理

问题1 方案：可继承AssetPostprocessor对资源改动的时候检查是否有开启读/写标记

问题2，3 ，4 方案：定期检查
其中问题2，3只需要判断颜色通道比较简单不做解释
问题4 解决：
1.遍历所有贴图用字典缓存找到重复的资源
2.找到项目下所有材质，并且缓存
3.找到引用该重复贴图的材质
4.判断该材质所有引用贴图字段如有和重复贴图相同则替换
5.删除重复贴图

代码：
