Global dissolve Shader

[rich valley]

Hello ! I'm new to Shaders so I'm trying to learn.
Here's my situation :
I have some prefabs with their own materials/shader. Is it possible to make a shader to make them dissolve on their left-side (Kind of like a thanos snap) ?
Since I want to keep the visual of my prefab I'm guessing I should use a Render feature, but when I do, the previous material is still visible below :/
I link my very simple dissolve left Shader.
I'd also like to know how to not provide colors in my Shaders so my object doesn't become gray :/
Thank you !
PS: I'm using URP

Render Objects has a material override mode
It can inherit properties with matching references, so if you're using URP the Lit shader you can get the URP Lit template from package manager samples and do the dissolve on that so all features and properties will match

If you're dissolving a custom shader, then you'd make the dissolve on top of that instead using the relevant properties

Render objects renders objects on top of what's there, so if you want to swap the object to dissolve using the override, I suppose you need to swap its rendering layer to one that's not rendered to avoid rendering it twice

Or just implement the dissolve directly into the shaders you're using to avoid messing with renderer features

So there's no way to make all my objects dissolve without overriding every material/shader ?

Let's say I take a house prefab, it means I have every material to be transparent instead of opaque and add my dissolve logic in its shaders ?

Not really a way around it
Making everything transparent is not practical if you need 3D sorting
Or performance

An opaque dissolve using alpha clipping is one option, but swapping to a material instance or changing keywords at runtime from a script could be better
