Pixelated Lighting Shader

[ember hinge]

I've got a great shader that I really like, and want to use Unity's builtin lighting, but pixelate it. I don't plan on using shadows, but I do plan on using lots of pixel lights. How could I go about this?

Pixelate it how, precisely?

[ember hinge]

The lighting on all surfaces should be pixelated to the same resolution as the base texture. Usually 32px/m for environment textures

Does that make sense?

This is probably what you're looking for

I see - this looks like a total nightmare, I'm not going to lie

I do have one other idea - is there a way to have vertex lighting, but without manually subdividing all the meshes? It could just automatically treat the mesh as subdivided every meter?

[solar nexus]

How does vertex lighting relate to subdividing?

[ember hinge]

if i put the cube on the left into the scene, it will be lit as though it was the cube on the right

vertex lighting an object as if it is more subdivided than it actually is

[solar nexus]

It would have to be something much different than vertex lighting technically I think

[ember hinge]

ok, that's alright

i'll try to do the per-texel lighting and if i can't figure it out then back to normal and evil vertex lighting

thank you for that link btw! appreciate it

[solar nexus]

What's the nightmare btw?

[ember hinge]

i'm just very new to shaders, i'm working in SRP, and i've never used the shader graph (and kind of don't want to)

[solar nexus]

"In SRP"?

[ember hinge]

standard render pipeline

[solar nexus]

The built-in render pipeline or BiRP you mean

[ember hinge]

i've seen it referred to as SRP

[solar nexus]

There is no "standard" but URP is the closest thing to that

SRP refers to "scriptable render pipeline" which is what URP and HDRP are

[ember hinge]

oh, my mistake

[solar nexus]

There was an unfortunate period of two months or so years ago when unity's own devs referred to birp as "standard render pipeline" which may have started the confusion that still lingers

[solar nexus]

Shader Graph may be easier than writing shaders if you're new to it
But if you have to modify an existing BiRP shader it will not help with that, and it won't really help with custom lighting either because its lighting functions are integrated
