Introduction
Welcome back to Vertex Mode.
Today, we’ve got a quick and handy tutorial specifically tailored to 3D artists working on their portfolios.
We will learn how to render Ambient Occlusion (AO) in Marmoset Toolbag 4.
Ambient Occlusion adds depth and realism to your models by simulating the soft shadows that occur in crevices and where objects meet.
Here, we can see the difference between the sequence with AO enabled and with AO disabled.
So, let’s dive right in!
Setting Up Ambient Occlusion in the Viewport
First, let’s discuss enabling Ambient Occlusion in your Marmoset Toolbag 4 viewport. This straightforward process lets you see the AO effect in real-time while you work.
- Open Marmoset Toolbag 4 and load your scene.
- In the upper left corner of the viewport, you’ll find dropdown menus for the Camera and the Viewport Display Quality.
- Click on the “Display” dropdown, which is likely set to “Full Quality.”
- Next, navigate to “Render Passes,” then “Lighting,” and finally select “Ambient Occlusion.”
This will allow you to see the AO in the viewport, but it will not be included when you render the image or sequence. Let’s switch back to “Full Quality” and learn how to render the AO pass.
