写了一个水波纹的进度条，但是编辑器和浏览器中显示不太一样

如题，这里编辑器中设置baseLine为0.5，且修改0~1也是按照想要的进度显示。如下图

但是浏览器中显示则要设置baseLine为0.05才会显示一半的进度，而且测试下0.0~0.12才是范围值。如下图

下面是实现的shader：

请大佬们指导一下，十分感谢~

补充：目前使用341版本

是不是动态合图没有关？看起来是uv导致的，你图片的这个Packable要关掉才行

你好~

而且浏览器效果跟我在编辑器中看到差别很大，现在这个baseLine设置是0.05

在387中浏览器和编辑器效果是一样的。
你给出的代码并不能直接使用，也没给出你的cocos版本，我复制你的核心部分到builtin-sprite下效果是一样的。

抱歉没有贴出来，我的是341版本，想问一下不能直接使用的原因是什么呢？

若干个include

代码最好不要直接复制粘贴出来，论坛上可以发特定格式的代码块（我不会），或者直接发文件/demo

前后加上三个```反引号即可
