阴影贴图太大了

Question

着色器贴图纹理中的一切都正常，但缩放（太大）。

坐标纹理：

mat4 bias = mat4（0.5,0.0,0.0,0.0,0.0,0.5,0.0,0.0,0.0,0.0,0.5,0.0,0.5,0.5,0.5,1.0）;

ShadowCoord = bias * projMatrix * viewModelMatrix * vec4（position，1）;

为什么在另一个例子中，textureMap坐标是：

ShadowCoord = bias * projMatrix * viewModelMatrix * ViewMatrixInverse;

另一个：

ShadowCoord = bias * projMatrix * viewModelMatrix * ModelMatrixRenderObject * vec4（position，1）;

有人能解释这些差异吗？为什么我的纹理贴图会被缩放？
