Free Ambient Occlusion in Maya tutorial for 3D animation students.
Ambient Occlusion in Maya, the term comes in case of Maya Rendering. Maya Ambient Occlusion render pass is one of the vital parts when rendering output for production pipeline is the subject with Mental Ray rendering system and it is directly linked with surface shader of an object. To prepare a scene for Ambient Occlusion you have to change the surface shader of the respective scene objects from the default lambert material. So, go through this Maya Ambient Occlusion tutorial. I think the Ambient Occlusion pass procedure is very easy to follow.
Let’s start the Maya Ambient Occlusion Rendering procedure.
To demonstrate the Maya Ambient Occlusion I used a car tire and a car tube object like the following image.
The above objects are created using the polygon modeling technique and placed in the perspective view. You can use any objects to go through this Maya Ambient Occlusion tutorial. This Ambient Occlusion in Maya tutorial proceed with the following topics.

Rendering Ambient Occlusion in Maya
1. Maya Render Settings Ambient Occlusion
As you know, this tutorial is to represent the Maya Ambient Occlusion, so the rendering platform should be the Mental Ray. So, open the render settings window from the right-top corner of the Status Line.
The Render Settings window appears. In this window select the mental ray option from the drop-down list beside the Render using category. Now, your current renderer is the Mental Ray and Render Settings window shows the properties of the Mental Ray rendering system. Here, select the mental ray tab and choose the ‘Production’ quality from the drop-down list as the Quality presets option. Production quality gives us the smooth production quality result when rendering. To follow this tutorial, we don’t need more modification in this Render Settings window. So, close it.
2. Maya Ambient Occlusion Node Setup in Hypershade
Open the Hypershade window from the Rendering menu. Find the triangle shape above the Create tab and click on it to reveal the hidden tabs of node categories. Here, select the Create All nodes option to get all rendering nodes at a time in this create tab.
3. Maya Ambient Occlusion Node Setup-2
Now, under the Create tab expand the Surface tab if it isn’t already expanded and click on the Surface Shader from the surface node icons. You can now see a Surface Shader node in the Hypershade tab as well as in the Work Area tab.
4. Maya Mental Ray Ambient Occlusion Shader
Now, find the Textures tab in the Create tab panel and click on the ‘mib_amb_occlusion’ node to create it in the Work Area tab. Here, double click on this node to open its attributes in the Attribute Editor window. In this Attribute Editor window change the Samples value to 256 from the default 16. More Samples value gives a smooth Ambient Occlusion result.
5. Connecting Ambient Occlusion and Maya Surface Shader Node
Now, place the two nodes (Surface Shader node and the ‘mib_amb_occlusion’) side-by-side in the Work Area tab.
Here, we have to connect the two nodes. So, drag from the ‘mib_amb_occlusion’ node to the ‘Surface Shader’ node while holding down the middle mouse button. After reaching the ‘Surface Shader’ node release the middle mouse. A marking menu list appears. Choose ‘default’ option from the menu. The connection building work between the two nodes completed. Isn’t it easy?
6. How to apply Ambient Occlusion Shader onto Objects
Now, apply the Surface Shader on the car tire and car tube objects. You can implement it in two ways. You can select the objects in the view-port while the Hypershade window still open. Then right-click on the Surface Shader node in the ‘Hypershade’ and choose ‘Assign Material To Selection’ option from the marking menu. Alternatively, you can just drag and drop the Surface Shader node from the Hypershade window to the objects using the middle mouse button.
7. Rendering Ambient Occlusion in Maya
Now, you will notice the objects are deep dark in the view-port. Don’t be afraid. Just render the scene using the menu Render > Render Current Frame. And you have completed.
