How to Add a Light Gobo in Maya

 

 

Using Photoshop to create a jpg file, you can easily define patterns, colors and shapes for your light source.

 

Step One

Open a new 500 pixel by 500 pixel document in Photoshop and draw using shapes and colors. Save the image as a jpg file in your Maya project's sourceimages folder.

Step Two

Open your Maya project with several objects in the scene.

Step Three

Add a spot light to the workspace (Create > Lights > Spot Light).

Step Four

Position the light with the Move Tool so it illuminates the scene. Press the t key to access the light's manipulator.

Step Five

With the light selected, open the Attribute Editor by clicking the Attribute Editor icon. Click the checker-box next to the color slider for the light.

Step Six

In the Create Render Node Box, right-click the File icon and choose Create Texture. This creates a file texture that is UV mapped to the object.

Step Seven

In the Attribute Editor, under file tab, click the folder icon next to the image name and navigate to find your jpg file. Render your image. Increase light intensity if necessary.

You can also use images, movies or textures to add texture and color to your lights. Consider this technique to create the illusion of light being cast from a stained glass window. Another possibility would be an underground cave where the light enters through a grate in the ceiling.
