WireframeShader: Applying Wireframe Overlay

The WireframeShader node allows you to render a wireframe overlay on the surface of your geometry object or particle simulation. This can be useful, for example, if you want to:

• check that your texture projection correctly lines up with your geometry.

• create a quick render of your 3D scene to check the positioning of objects.

• create motion graphics.

• create "making of" videos.

Note:  The WireframeShader node currently only works if you are rendering your 3D scene using ScanlineRender.

1.

Insert WireframeShader node into your script.

2.

Place the WireframeShader node between your 2D texture image and your 3D object node, or connect it to a GeoBindMaterial node’s mat input.

3.

In the WireframeShader properties, use the channels dropdown menu to select the channels you wish to process.

4.

From the operation dropdown, select how to apply the wireframe overlay to your geometry:

• opaque - display the wireframe on fully opaque black input geometry.

• over - display the wireframe on top of the input shader or texture.

• multiply - multiply the wireframe by the input shader or texture and display it on fully transparent geometry.

• modulate - apply standard diffuse shading to the wireframe and display it on top of the input shader or texture. This takes into account any lights in the scene.

5.

To set the width of the wireframe lines (in pixels), adjust line width.

6.

To set the color and transparency of the wireframe lines, adjust line color.
