任何人都可以告诉我为什么会收到此错误:
当前顶点声明不包括当前顶点着色器所需的所有元素。缺少 TextureCoordinate0。
使用标准的顶点着色器,一切都很好。
这是我的着色器文件:
float4x4 World;
float4x4 View;
float4x4 Projection;
float4 color;
float seaLevel;
texture myTexture;
float maxHeight = 128;
float height;
sampler2D mySampler = sampler_state
{
Texture = <myTexture>;
MinFilter = Point;
MagFilter = Point;
MipFilter = Point;
AddressU = Clamp;
AddressV = Clamp;
};
