About

SOM occluders are needed to calculate the occlusion of the sound, since the sound engine cannot do this in real time. The occlusion will be calculated depending on the Game Material settings.

Start

For example, let's create such an object for a building with a large space inside.

Building example:

Create a mesh that simply represents your model.

tip

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

Surface

Go to Material Properties.

Create a separate material for our SOM occluder.

note

If you go to have the sound cut off on both sides, select the 2 Sided flag

In X-Ray Engine: Material choose:

Shader

Choose 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

Choose or create new Game Material

Game MaterialTechnical Terms

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

note

In Game Material for the SOM occluder the main factor will be Sound occlusion

Finish

Go to Object Properties.

In X-Ray Engine: Object select Sound Occluder in Type list.

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