Real-time Effects

Staring down into the dim and horrible cave, suddenly you hear a faint humming. It sounds like distant breathing and seems to get louder for every breath. Suddenly a frightening Evil Head charges out of the cave, with an open mouth brandishing sharp teeth.

While the Evil Head dashes past the Adventurer, it emits a constant Hover sound, added to provide auditory feedback of the Evil Heads position. Their movement speed is translated into the frequency of a Wwise Tremolo Effect. As you might have noticed in the previous section, the Integrity Report was reporting an issue with the EvilHead_Hover_LP Sound SFX. Let’s generate a new Integrity Report.

  1. In the Integrity Report’s Report group box, unselect all options except Optimization, and click Generate.

    In the Status column, you’ll see a message indicating that an RTPC has been applied to the Effect, and therefore, it won't be rendered. When an Effect is rendered into an audio source, the Effect will become fixed and can’t be changed at runtime. As such, if you apply runtime influence, the render functionality will automatically be ignored and shown in the integrity report. Let’s now remove Render from the Effect.

  2. Select the EvilHead_Hover_LP for any platform.

  3. Close the Integrity Report, and in the Property Editor’s Effects tab, disable Render.

    If you generate a new Integrity Report, it’ll become blank and you’re now sure no Effects are set to render while they are influenced by runtime mechanics.
