Toon material

IHi everyone, im trying to make a toon material with outline effect for my character(and only my character), there is a way to do with by using only the character material and lights scene ? I dont like to use the post process method because i draw by myself the the diffuse textures for my environment assets, so i want to use a toon material with my own diffuse texture with black outlines only for my character.
Thank you :slight_smile:
