我将我的monogame升级到最新版本。首先在流水线工具中构建着色器时,出现错误顶点着色器'SpriteVertexShader'必须是SM 4.0级别9.1或更高!所以我改变ps_2_0到ps_4_0_level_9_1但现在我得到的错误:升级MonoGame,现在我无法让我的着色器编译
错误X3004:未声明的标识符“SecondPassTextureSampler”
任何人有关于如何解决这个问题的想法?

您的着色器看起来不像GLSL;什么是'技术'和'传球'?另外,'SecondPassTextureSampler'不会出现在着色器中;你确定这是你的着色器失败,而不是你的C#代码吗? –
谢谢你的采访。 techinque和pass均来自我链接的XNA宏。 SecondPassTextureSampler get的自动创建我认为。我甚至没有运行C#代码,只是Monogame管道工具。 –
