URP - Unlit shader that can receive shadows

Hi,

I have an environment that uses painted textures and I don't want the colors to be affected by light sources so an unlit shader works great for it. I created one using Shader Graph and all it has is a Texture2D node which goes to a Sample Texture 2D node which connects to the color.

I also have a few characters that travel through this environment and I would like them to cast realtime shadows on it if possible. By default this doesn't seem to be possible. If I change the environment shader from an Unlit Graph to a PBR graph it works, but now the colors of the environment are affected and that can't happen.

I'm quite bad with shaders, is there any simple solution that I could implement or am I stuck without shadows for now?

Thank you!

in Unity 2021.2 version.
it didn't receive shadows.

 

Is there any update on this? I don't see any out-of-the-box support for receiving shadows for Unlit shaders in shader graph.. (Unity 2022.2)

[EDIT]
Ok, found a workaround from this video tutorial:
