Overriding a Texture on a Pencil Line

A pencil line can be drawn with a texture but also painted with a texture swatch. With the Colour-Override node, you can override the pencil line's texture or texture fill and replace it by another one, or you can animate the texture's position.

With the Edit Gradient and Texture tool, you can modify the size and position for both types of textures on a pencil line; the drawing texture and the filling texture. By doing that, you are actually modifying the texture's matrix.

Modifying a Texture Fill on a Pencil Line

When you paint a pencil line with a bitmap colour swatch, you can override the position of the texture fill using the Colour-Override node and a Peg.
