Overview

This tutorial explains how to make use of Occlusion setting in FMOD Studio. There are two ways of setting up occlusion to work with CRYENGINE:

Setting up Occlusion using a Lowpass Effect

The first and simple way is to add a FMOD Lowpass Simple or FMOD Lowpass effect to the Master Track. Make sure to set the Cutoff frequency to the maximum of 22 kHz.

Setting up Occlusion using a Parameter

Another way is to use a Parameter, even though it takes more time to set up but allows more control over how the sound changes when it gets occluded.

To add a parameter:

• Add an occlusion parameter with a range from 0 to 1. You can leave the initial value at 0, which is set when the sound is not occluded.
• In the Occlusion Parameter tab, add automation for volume, lowpass filter or any other effect that should change the sound when it gets occluded.
• Create an occlusion audio system RTPC in the Audio Controls Editor and assign the occlusion parameter of the FMOD Studio event to it.
