    Hello everyone, I'm new to URP. Now I want to render the depth of scene to a
    RenderTextureFormat.RFloat format RT instead of depth or shadowmap. The question is when I modifty the fragment shader of ShadowCasterPass, return the depth of the fragment like this:

    when ColorMask is zero, i get nothing in color channel,but all in depth buffer

    when i set colormask to A,erverthing works fine,the depth information write to the RT correctly ,but the scene looks horrible

    because every fragment's color is it's depth.
    I just want to know if there is a way like inversed colormask so that only write to the RT?
