Changing material (Instance) properties has no effect [URP]

I'm trying to change the priority of my custom shader based on a URP / Lit shader. I only changed Ztest in it to Always for overlay drawing. The shader works as I need it, but only if I change the priority manually in the editor. If I do this through code, then changing the priority has no effect until I expand the material settings in the editor (in other words, the priority that I set with the code applies to the material, but does not affect the rendering in any way). This applies to any other properties. The build also has this problem.

This is how I change the priority:

Code (CSharp):

1. mat.SetFloat ("_QueueOffset", mat.GetFloat ("_QueueOffset") + 2);

The shader I'm using:

Spoiler: Shader

Code (CSharp):

1. Shader "Universal Render Pipeline/Overlay Lit"

_ QueueOffset

is not the same as

_QueueOffset

 

Sorry, this is a typo in the post, it is not in the code.

 

Unfortunately I honestly have no idea how the queue offset is actually applied. Looking over the code I only see it setting that queue value. There are other parts that show it only shows the queue offset if there's also a

_QueueControl

property, but very few of the included shaders have this property and yet still show the queue offset, so I have no idea what's going on.

 

In that case, maybe you know a working way to render a mesh on top of everything in URP? Perhaps using ZTest isn't the best way? To be honest, I'm pretty bad at shaders and rendering as such.

 

The easiest one is to turn on the second camera, put it at the very bottom of the stack. Assign in the Culling Mask the layer that it will render, and assign this layer to the object. Well, and accordingly, uncheck this layer from your current camera.
