Help Wanted Post Processing - how to draw texture onto CameraDepthTexture?

    I'm using the URP so don't have access to Light Cookies, but I was wondering would it not be possible to simulate the same effect by using a post-process effect to achieve the same effect using the Camera Depth Texture?

    I have very basic knowledge of shaders, but from what I understand I would need to get the directional light matrix and UV positions?

    Code (CSharp):
    1. float2 lightSpaceUVs = mul(unity_WorldToShadow[0], float4(, 1)).xy;
    2. half4 caustics = tex2D(_CausticsTex, lightSpaceUVs);
    If that is correct then how do I go from that to applying it over the Camera Depth Texture?
