Waveform Overlay draws a lightweight luma waveform inside a movable overlay box. It includes grid lines and texture labels for 0, 25, 50, 75, and 100.

Tips
- Use Overlay Position to keep the scope clear of important picture content.
- Increase Waveform Samples for more detail, but keep an eye on render time.
- Raise Noise Reduction if the trace looks too fuzzy.
- Put this layer last when you want the waveform visible over the final output.
