From the Layouts menu, select Designer.

In the Project Explorer's Audio tab, expand Master-Mixer Hierarchy > Default Work Unit > World > AUX > Region_Dungeon and select the Dungeon_Library Auxiliary Bus.

On the Object Tab’s Effects tab, go to the RoomVerb row (ID 0) and click the Pop Out button.

In contrast to Matrix Reverb, RoomVerb is packed with various controls.

Most relevant in this certification is the optimization properties: Quality, Density, and Room Size. These three properties directly influence how much memory is needed to process the Effect. An estimate of the memory usage is shown in the bottom-right. Using the Density and Quality properties, let’s now reduce the estimated memory usage to 300 KB or less while trying to maintain the best possible quality.

In the Actor-Mixer Hierarchy, expand Actor-Mixer Hierarchy > Default Work Unit > World > Player > Player and select the Player_Pickup Switch Container.

In the General Settings tab, go to the User-Defined Auxiliary Sends group box and, if not already enabled, enable Override parent.

If you’ve just completed the Matrix Reverb section steps, you should already have the PineForest_Hut in a slot. In the next step, make sure that the new bus is dragged on top of the PineForest_Hut slot, so you’ll only end up with 1 Auxiliary send.

Now drag the Dungeon_Library Auxiliary Bus into the first row (ID 0).

Return to the Dungeon_Library Aux Bus’s RoomVerb and adjust the Quality and Density properties until you’re at 300 KB or lower.

Changing property settings will always be a balance of optimization and quality, so try to change the properties so that you preserve as much quality as possible, but stay below the 300 KB limit. Constantly try to evaluate whether the lowering of a certain property affects the quality too much, and whether you could get a better result with the same optimization, from adjusting other properties.

Close the Effect Editor, and in the Transport Control, press Play to evaluate your property changes.
