Unity Shader Graph Basics (Part 7 - Custom Lighting)

Показать описание

Although the Unlit shader type doesn't automatically add lighting to objects, we can implement our own lighting however we want. In this tutorial, learn how to add a Fresnel highlight to the edges of objects and create a basic cel-shaded effect which implements and augments diffuse lighting.

I'm using Unity 2022.3.0f1, although these steps should look similar in previous and subsequent Unity versions.

You have been explaining topics very well! Well done Daniel 👏

I didn't know there was a built in Fresnel node. I've rebuilt that functionality and made my own sub-graph. That's awesome to know!

An interesting thing to do if you want to control the shadow color of the object for a more specific use. Instead of using a float property for the light strenght, you can use a color property instead.

I didn't know about the main light direction node. That's better than making a custom HLSL script just for this calculations!!

You know if there is something similar to additional lights already implemented?

Thanks a lot for the tutorial! I did the same things, but my sphere doesnt glow outside of it. Are you using a bloom effect? Or are you using HDRP?
