Documentation / scene / PannerNode

Class: PannerNode

Defined in: libs/scene/src/utility/blueprint/material/texture.ts:790

UV panner node (scrolls UVs over time)

Remarks

Computes: coord + time * speed

If Coordinate is not connected, the node defaults to mesh UV0 in IR. If Time is not connected, the node defaults to elapsed time in IR.

Inputs:

• Coordinate (vec2)
• Time (float)
• Speed (vec2)

Output:

• Output 1: Panned UV (vec2)

Example

const panner = new PannerNode();
panner.speedX = 0.1;
panner.speedY = 0.0;

const tex = new ConstantTexture2DNode();
const sample = new TextureSampleNode();
sample.connectInput(1, tex, 1);
sample.connectInput(2, panner, 1);
