Creating a Fog-of-War like shader/system in URP

I am trying to make a fog of war like shader/system in URP. I posted this on the Android forum because it is critical for me that this is Android friendly, and I have made some progress on my own, but I'm really pushing my limits on knowledge and understanding here with the render features and shaders. If anyone takes a look at this thread, and has any opinions, feedback, suggestions, or otherwise, I would greatly appreciate the help.

Android friendly fog-of-war-like shader/system - Unity Forum

Thanks in advance!

 

@eizenhorn recently posted about his solution to this in a thread over here. Perhaps he'll be kind enough to chime in with a few extra implementation details about his shader work!

 

Came back to bump this. My linked solution above is having issues on Android where the "fog" flickers in and out pretty bad. I don't think I know enough about the render features to do any better. Still looking for some help if anyone has any advice. For now, I'm just going to save the render texture output of the camera to a texture2d and set that as the texture on the plane's material.

 

Which device? Are you on GLES or Vulkan?

 

Test device was a OnePlus Nord N10 (BE2028). I don't see it on the list of supported GPUs for Vulkan, so I'm going to guess its OpenGL.
