 STEP 02

Go to Zplugin > Multi-Map Exporter.

On the screenshot below I highlighted the areas that you should pay more attention while adjusting your settings.

  1. Check the Ambient Occlusion
  2. Option Select the desired resolution
  3. Click on File Names and choose your UV tile ID format

Here you can find the main settings for your Ambient Occlusion. The settings above are the ones I usually use, but it takes a lot of trial and error. Below you can see the information from the Zbrush Documentation website

Occlusion Intensity: This slider increases the Ambient Occlusion Intensity making the ambient occlusion areas larger and darker.

ScanDist: Scan Distance increases the distance of the secondary color in the Ambient Occlusion.

Aperture: Aperture affects the scale of the Ambient Occlusion, with smaller values giving a softer affect.


STEP 03

After adjusting the settings, just click on Create all maps.

Here’s the Zbrush AO map preview in MARI.
