Cel/Toon Shader in Unreal Engine 5

I recently quit my job and have been thinking on continuing my career as a technical artist. So I'm studying and try to update my portfolio using Unreal Engine 5. This is something I created during my learning process.

There are 3 different materials. 

• M_CelBase is a toon shader with only colors.
• M_CelBase_Texture is more advanced material that using textures.
• M_Outline is an addition to M_CelBase_Texture for dark lines on edges to make it look more toony.
