Shader is opaque but shadows visible through shader (image provided)

Hi I am have a real issue here, made a water shader that needs to have is surface setting as transparent in order to use the camera depth utility to create a water foam effect around objects intersecting the water plane. However I dont want to see the objects beneath the water surface. So I put the alpha of the water shade to 1. Yet I can still see a dark outline of objects beneath the water surface. When I turn off shadows, this disappears. Can anyone help? Thanks. I also tried toggling “receive shadows” on and off for objects, which apparently does absolutely nothing in the version I am using (2019.3)…

This is a long time bug that’s been fixed by Unity already, I think in URP 7.1.7. I’m not sure if that version of the URP is exposed to the Package Manager, or which versions of Unity it works with. My guess is it requires 2019.3 or better.

Thanks for the reply! Unfortunately URP 7.17 is installed in my project and the LWRP is removed. This has not resolved the problem, unfortunately.

Honestly, I don’t entirely understand how they post new builds, but you’re right it looks like it isn’t in 7.1.7 either.

The bug was fixed in a branch that was supposedly merged into the master branch on Nov 28th
https://github.com/Unity-Technologies/ScriptableRenderPipeline/pull/4979

Version 7.1.7 was labelled & released a little over a week and later, but does not appear to have those changes yet. So, not sure what version it’ll be released in.
