The value should be as high as the maximum possible displacement value, so it is safe to assign here the same value as the multiplier used in the RenderMan Code above (in this example, the multiplier is ‘2’).

In the Displacement group, assign a value for the 'Displacement Bound' attribute.

Click on the AE button to edit this node in the Attribute Editor.

In the A ssignment Panel, create a geometry attribute node by clicking on the texture button next to the Attribs option menu.

Make sure your polygon shape is selected.

Bring up the Assignment Panel by selecting its entry in the 3Delight menu (or by clicking on the Assignment Panel button in the 3Delight Shelf).

Because we are doing displacement, we need to specify a displacement bound.

Assign the material you just created to your polygon shape.

Connect the 'displacement' output plug of the Displacement node to the 'displacementShader' plug of the shading group connected to your surface node.

Connect the 'displacement' output plug of the RenderMan code node to the 'Displacement' input plug of the Displacement node.

Note that you can increase or decrease the multiplier value to make the displacement more or less obvious. This line simply assigns to the displacement output plug two times the alpha channel of the 'displacementColor' color set.

Create a RenderMan Code node (listed in the Utilities section) and then select the RenderMan Code node and bring up the Attribute Editor.Ĭlick on the Text Editor button next to the Shading Parameters text field and append the following lines in the text editor:ĭisplacement = 2 * displacementColor_alpha.

Bring up the Hypershade Editor and create a surface node, such as Blinn.

The surface is going to be displaced where you paint you can adjust the Opacity slider and check the Accumulate opacity checkbox if you want.

Since we are only going to use the alpha channel of this color set, use any color you want, but make sure the Channels radio button is set to ‘RGBA’.

Back in the Color Set Editor, select the displacementColor color set.You can try varying the opacity slider while painting in ‘RGBA’ mode. In the Color menu, select the Paint Vertex Color Tool item.Paint the surface as you like, leaving some visible areas unpainted.Name a color set ' surfaceColor' and name the other color set ' displacementColor'.In the Color Set Editor, create 2 color sets using the New button.In the Color menu, select Color Set Editor.Select the polygon shape and select the Polygons menu set.Create a polygon shape of your choice, and light it with a few spot lights.

The following example shows how to export vertex colors additionally, the RenderMan Code node will be used to visualize the color sets in a rendered image.
