新人疑问贴，我想修改一个builtin-sprite.effect，一打开就报错

Creator 3.x
#1

[Assets] …/Water/Shaer/water-sprite.effect - type error: Error EFX3302: illegal property declaration for ‘tiling’: no matching uniform

[Assets] D:\Cocos Dashboard\NewProject002\library\50\501da819-0716-4c52-9e5d-f4653f2602d6.json: ENOENT: no such file or directory, open ‘D:\Cocos Dashboard\NewProject002\library\50\501da819-0716-4c52-9e5d-f4653f2602d6.json’

[Window] The “path” argument must be of type string or an instance of Buffer or URL. Received undefined

一修改 effect 材质文件，就报错，然后文档实在是看不懂 ，，，用 VS 打开材质文档，也会说Not a valid engine path,

你看看 tiling 有没有对应的 uniform 声明。
