Procedural Painterly Cel-Shader Material

Disclaimer: This material is intended for use in EEVEE. A procedural painterly cel shader material that takes some elements from Joey Carlino's "2d style materials in 3d animation" and TheSicklyWizard's "Stop Using Color Ramps For Toon Shaders" tutorial videos. I have made some modifications from the original materials to better fit with the style I wanted to use for my models. There are more setting options in the procedural painterly normal node group to allow for more customization in the painterly effect. I typically turn up the noise distortion slider to make the texture look like brush strokes (I recommend a maximum of 1 as anything higher looks weird from my experience). There is a node group that that allows for the customization of the shadow and highlight colors. This can be done with the two rgb curves within the Cell Shadow node group. The cell shader converter node group also has some float curve nodes within it that you can also mess around with. The nodes that are recommended to change within the cell shader nodes are placed in yellow frames titled edit these for more clarification on what is recommended to change. The material is also compatible with the principled BSDF node's metal and glass settings, although it should be noted that there seems to be no way to have other objects render behind the glass.
