It's a standard lit shader from Unity's (2022 LTS) URP along with post-processing settings, I also didn't bake the lights, they are realtime, that way the moving ones don't act weirdly. I've made custom shaders for past projects but for this one fortunately i didn't have to.
Check this tutorial if interested, keep in mind mine are not baked and i didn't need to add a point light to any of the props, the emissive material is the only thing that i've needed for mine, set in a similar way:
Thank you for checking out Un-LIT, I'm glad that you've liked it! :D
