Effects
Bulge
Pushes the picture outward or inward from the centre.
The Bulge node magnifies the middle of the frame, or shrinks it for negative values, with a soft falloff.
- One signed control, Amount
- Found in the node graph under Post FX → Warp
The image on the right is the example patch itself. Drag and drop it onto the app, or load it with File → Load, to open the full graph. A Caustics field, run through a Gradient Colorizer, at the default of 0.
Inputs and outputs
| Port | Type | Purpose |
|---|---|---|
| Input | Texture | The picture to process. |
| Output | Texture | The result. |
Parameters
Opacity, Blend Mode, and Alpha are the standard operator header; see Parameters and Controls.
- Amount (−1 to 1, default 0) — positive bulges outward, negative pinches inward.
Every slider has a per-parameter animation bar, so it can be animated, audio driven, or MIDI mapped.
Examples
Pulse — drive Amount from a Sound modifier so the frame breathes with the bass.
Troubleshooting
You want to move the centre — Bulge is always centred. Use Pinch, which has Center X / Y and a radius.
