About

HOM occluders are essential for optimizing levels. They remove the geometry in the occluder.

Start

For the tutorial, the creation will be for Static Object, but HOM occluders can also be used for other purposes (e.g. for tall view bounders, hills, etc.). Let's take this as an example:

All we need to do is create a mesh that simplistically represents our model:

tip

You can simply duplicate your model, but remember that the fewer polygons and the better HOM Occluder represents your model, the better.

Surface

Go to Material Properties.

Create a separate material for our HOM occluder.

In X-Ray Engine: Material choose:

Shader

Any Engine Shader

Engine ShaderTechnical Terms

Shader responsible for the visual appearance of the surface.

for Static Object (list of all Engine Shaders )

Compiler

Any Compile Shader

Compile ShaderTechnical Terms

Shader used by the Level Compiler. Specifies to the compiler the features of the final game level geometry. The source geometry, depending on the Compile Shader, may have different features.

Material

Any Game Material

Game MaterialTechnical Terms

Responsible for the physical feature of the surface (friction, damping, etc.).

(Example materials/occ - This material does not include rendering parameters that are unnecessary for the calculation) (list of all Game Materials )

Finish

Go to Object Properties.

In X-Ray Engine: Object select HOM in the Type list.

This completes the setup of the HOM Occluder. You can safely export it in the model format you need.
