Exploring NPR Shaders in Blender: Stipple Texturing

Are you ready to dive into the fascinating world of NPR shaders in Blender? In this inaugural episode of our series, we will be focusing on the intricacies of stipple texturing. So, fire up Blender, switch to Eevee, and let's get creative!

Setting the Stage

Before we kick off our stipple texturing adventure, ensure that you are in Eevee mode. Adjust the Cube and Cascade size settings while disabling soft shadows for optimal results.

Creating the Stipple Shader

  1. New Material: Start by creating a new material for your object.
  2. Shader Setup: Add a few shaders and route them through a Shader to RGB node.
  3. Color Amplification: Introduce a Color Ramp node with a constant interpolation. Define the color stops according to your preferences.

Pro Tip: Utilize resources like Adobe Color to discover stunning color palettes or craft your own unique combinations.

Implementing the Stipple Texture

  1. Voronoi Texture: Generate a Voronoi texture. Enable Node Wrangler for efficiency.
  2. Mapping and Scaling: With Node Wrangler activated, use Ctrl T to establish a mapping and coordinate node. Opt for object coordinates and adjust the scale of the Voronoi texture.
  3. Shader Integration: Connect the distance output of the Voronoi texture to the color input of the Diffuse Shader.
  4. Fine-Tuning: Experiment with the Color Ramp stops to achieve the desired effect.

Adding Animation to the Stipples

To infuse dynamic movement into your stipple texture:

  • Switch the Voronoi texture to 4D.
  • For animated stipples, input "hash(frame) / 2000" as the seed value.
  • Adjust the numerical value to control the speed of the seed's transformation.

Unleash Your Creativity!

That's a wrap! Now, unleash your creativity and apply the stipple texture to diverse elements. Whether it's Suzanne the Monkey, a majestic horse, or a towering mountain, let your imagination run wild with stipple texturing.

Have fun experimenting with this technique and stay tuned for more exciting NPR shader breakdowns in the upcoming episodes. The world of Blender NPR shaders is brimming with endless possibilities—explore, create, and inspire!
