Rendering a scene that has been colored with the Color at Vertices tool requires a few extra steps. You must apply a map lookup shader to the painted object in order for the colors applied to vertices to render. Use one of the following shaders:
• Vertex RGBA is a map lookup shader that outputs any color at vertices map as a color value that you can plug into other shaders. You can output either all of the RGBA channels or only the Alpha channels.
• Color Map Lookup is a map lookup shader that outputs any type of texture map, including color at vertices maps, as a color value that you can plug into other shaders. You can multiply the map by a factor that you specify.
To render color at vertices
1. Select the object(s) that have been painted and do one of the following.
- From the Render toolbar, choose Get > Texture > More to display a browser listing additional texture shaders. Choose the Vertex RGBA shader from the list.
or
- From the Render toolbar, choose Get > Texture > Map Lookup. The Map Lookup Color property editor is displayed.
2. From either shader’s property editor, select the color at vertices map that you applied to the selection from the Map list.
3. Draw a render region (press q) around the selection. Whatever you painted on the selected object(s) is rendered.

• If you only want to render the alpha channel of the color at vertices map that you painted on the selection, you must use the Vertex RGBA shader and make sure to activate the Alpha Only option from its property editor. • Though the previous steps explain how to render color at vertices shader using Render toolbar commands, you can also use any of the other methods described in Three Basic Texturing Methods. |
