Create a 3D sketch

Apply a sketch to a 3D model for a painterly rendered image.

Project Sketch is a convenient method of previewing a surface that you have created with the aid of a 2D sketch image plane. Sketch render converts the image plane to a shader and assigns it to the model.

Using a sketch projection

When you use a sketch projection on a model, the following processes are automatically performed:

If there already exists a shader named SketchProjection (for example, from previously performing a sketch render), then it is replaced with the new shader.

A new shader named SketchProjection is created in the Multi-lister based on a projection of the image plane along the camera’s normal. That is, the new shader has a Projection texture mapped to its Color parameter, the Projection texture has a File texture mapped to its Source Texture parameter, and the File texture has the image plane file mapped to its Image parameter. You must have an image plane defined in order to use Project Sketch.
The new shader is assigned to either all or select surfaces, depending on the option chosen in Canvas > Project Sketch.
If there are no lights in the scene, place some by using Render > Create Lights > Create Defaults or by placing specific lights.
At this point, you can render the surfaces, using Render > Direct Render, WindowDisplay > Hardware Shade, or Render > Render.

If you perform another sketch render, the SketchProjection shader will be replaced. If you wish to keep a sketch render shader, rename if before performing another sketch render.
