How to Self Illuminate a Texture in Maya

 

 

There a a couple of ways to make an object illuminate on it's own in Maya. The first is to use a Surface Shader and the second utilizes the shader's Incandescence setting.

 

Step One

Open a new Maya document and start a new project. Be sure to set your project and save your new scene. For more information, see topic, Starting a Project.

Step Two

Add two NURBS planes to the stage by choosing Create > NURBS Primitives > Plane.

Step Three

Using the Move tool (w key) move the second plane to the right of the first plane.

Step Four

In Photoshop, create a 1,024 pixel by 1,024 pixel RGB image with graphics and save it as a jpg file in your project's sourceimages folder. Name your file image01.jpg.

Step Five

Create a second 1,024 pixel by 1,024 pixel RGB image that is medium gray with a series of white rectangles. Save it as a jpg file in your project's sourceimages folder. Name your file image02.jpg.

Step Six

Returning to Maya, select the first plane, then right-click the plane and choose Assign New Material > Surface Shader.

Step Seven

In the Attribute Editor, surfaceShader tab, click the checkerbox next to the Out Color slider to open the Create Render Node panel.

Step Eight

In the Create Render Node, 2D Textures section, right-click the File button and choose Create Texture.

Step Nine

In the Attribute Editor, file tab, click the Folder icon to navigate to your image01 file in the sourceimages folder.

Step Ten

Select the second plane, then right-click the plane and choose Assign New Material > Blinn.

Step Eleven

In the Attribute Editor, blinn tab, click the checkerbox next to the Incandescence slider to open the Create Render Node panel.

Step Twelve

In the Create Render Node, 2D Textures section, right-click the File button and choose Create Texture.

Step Thirteen

In the Attribute Editor, file tab, click the Folder icon to navigate to your image02 file in the sourceimages folder.

Step Fourteen

Click the Render Current Frame icon to render your image. At this point the scene appears to be illuminated by the default light.

Step Fifteen

Click the Render Settings icon, then click the Common tab, Render Options section in the settings window. Deselect the Enable Default Light checkbox. This turns off the default light.

Step Sixteen

Click the Render Current Frame icon to render your image. The objects are self illuminated.

Spaceship Windows

This method can be used to simulate the windows of a spaceship. The incandescence map is a grayscale RGB image where white glows and black has no effect.
