Samples a texture with distorted coordinates from a given vector field, also known as a flow map.
Inputs
| Name | Type | Description |
|---|---|---|
| MainTexture | tex2D | Main texture that will be distorted |
| Main UV Coords | float | Base coordinates that will be offset by the vector field |
| VectorFieldTexture | tex2D | Flow map texture |
| Vector Field UV Coords | float | Flow map UV coordinates |
| Flow Strength | float | Multiplier on the flow map that offsets the main UV coords |
| Flow Speed | float | How fast to animate the main UV coords |
Outputs
| Name | Type | Description |
|---|---|---|
| Color | color | Sampled color from the main texture |
Properties
| Name | Type | Description |
|---|---|---|
| Main Coords Mode | dropdown | Choose what source to use for the Main UV Coordinates. If "UV Coord 0" or "UV1 Coord 1" are selected, the respective surface UV set will be used. If "Custom" is selected, the Main UV Coords input will be exposed and used instead |
| Vector Field Coords Mode | dropdown | Choose what source to use for the Vector Field UV Coordinates. If "UV Coord 0" or "UV1 Coord 1" are selected, the respective surface UV set will be used. If "Custom" is selected, the Vector Field UV Coords input will be exposed and used instead |
