Hello taylor,
Deathrey is correct is saying that you want to look at the stylized project provided in the learn tab. I’ve actually recreated the effect already (could use some more work) and am willing to provide the texture used and a screenshot of the material graph as well as some screenshots of it in use.
Here is what the material graph looks like, you need to use a material set in the postprocess material domain and then apply it as a blendable in your post process.
This is the texture sample used, it’s a .png so you will need to download it and add it to your project.
Keep in mind this type of effect wont work on unlit materials as well as can’t handle specular information as is.
Let me know if that helps,
