是不是让你在properites里声明一下customUniform和param

#3

弄明白了
你需要这样写：

uniform FragConstants {
    float customUniform;
    vec2 param;
  };
#4

声明了还是一样

搞哭了

#8

这提示不是很明显了么？
缺少分号
uniform FragConstants {
vec2 projectionVector;
vec2 center = vec2(-1.0, 1.0);
};

#9

sampler不要放进去，其它的要放进去。
你要看下错误提示啊

哎

为什么不直接用glsl 然后传个参数 好调试多了

我推荐你看下这个：

萌新认真请教,请问写好后要怎么用TS调用这个函数?(在Update中改projectionVector)
