RTPC Curve Switching Based on State

Question

Currently, RTPCs allow us to define curves to control properties based on a Game Parameter. However, in certain situations—especially during camera-driven or cinematic scenes—we need to apply a different RTPC curve depending on the game state.

For example, during a cinematic camera sequence, I want to lower the volume or apply a low-pass filter to sounds that are located outside the camera’s visible area (e.g., character movement or environmental sounds behind the camera). During normal gameplay, I don’t want this attenuation or filtering to occur.

It would be extremely useful if Wwise allowed us to switch between multiple RTPC curves (Curve A, Curve B, etc.) based on the current State or State Group.

Proposed Behavior:

• Each RTPC could have multiple curve sets.
• A specific curve set is automatically selected according to the active State.
• For instance:
  • Normal State → Angle RTPC uses Curve A (−10 dB off-axis, 20 % LPF)
  • Cinematic State → Angle RTPC uses Curve B (−25 dB off-axis, 50 % LPF)

Benefits:

• Simplifies workflow for dynamic camera and cinematic control.
• Avoids maintaining duplicate RTPC parameters for similar logic.
• Enhances creative flexibility for sound designers working with visual direction changes.

Considerations:

• Smooth transition handling when the State changes.
• Clear UI for managing multiple RTPC curve sets per property.
