Oil paint style shader that reproduces brush strokes

Structure

The base is created by processing the Voronoi texture like a brush stroke and using it for the normal and color.

The processed shader is converted to color using the Shader to RGB node, and colored using a color ramp.

Note

• Available only with Eevee Render.
  (Because it uses the "Shader to RGB" node)
• It is possible to bake the entire image by baking the nodes before "Shader to RGB" in advance.
  However, this can result in a slightly different impression.

• It cannot be used to for UV coordinate and image textures.
