Volumes Content Examples

Overview of the samples provided in the Volumes Content Examples.

The Volumes Content Example map illustrates how you can use different types of Volumes to produce different gameplay effects, set boundaries, improve performance and (or) reduce lighting build times. As seen in example 1.1 below, you can place a Volume by selecting any Volume from the Volumes Tab and dragging and dropping it into your level. Based on the type of Volume used, different settings may be available for editing.

The most commonly used Volumes for gameplay purposes would be Blocking Volumes (to keep players confined to your play space with invisible collision), Physics volumes to add gameplay effects like decreasing/increasing gravity or simulating being under water, or Pain Causing Volumes used to inflict burst or tick damage to the Actor that enters it.

Volumes Map


Listed below are the examples provided inside the Volumes map:


What is Demonstrated

1.1 Placement

Describes how to place a Volume in your level and how to edit it in Geometry Editing mode.

1.2 Blocking Volume

Demonstrates a how invisible collision can be created by placing a Blocking Volume in your level.

1.3 Cull Distance Volume

How to make a rule set for Cull Distances depending on the size of the objects (e.g. have objects hidden based on distance to the player).

1.4 Lightmass Importance Volume

Generates indirect light samples at player height for Dynamic objects within the volume and speeds up light rebuild times (e.g. typically used to enclose a playable area).

1.5 Lightmass Character Indirect Detail Volume

Similar to 1.4, however this generates indirect light samples within the entire volume not just at player height (e.g. used in elevator shaft to ensure indirect lighting is correct when it moves).

1.6 Precomputed Visibility Volume

A performance optimization, this stores the visibility of Actors for its location in the world (note: should be placed only in areas a player could access).

1.7 Precomputed Visibility Override Volume

This allows you to manually override the visibility of a Precomputed Visibility Volume if the auto generated visibility is undesired.

1.8 Physics Volume

Override the physics settings of an Actor that enters the volume (e.g. can be used to simulate a loss of gravity or used to simulate being underwater).

1.9 Pain Causing Volume

Actors that enter a Pain Causing Volume register and receive damage events (e.g. can be used to apply damage from a fire).
