| stream | The name of the custom data stream to apply the curve to. |
| component | The component index to apply the curve to (0-3, mapping to the xyzw components of a Vector4 or float4). |
| curve | The curve to be used for generating custom data. |
Set a MinMaxCurve, in order to generate custom data.
