The |
| 1109 |
|
Vname is the coefficient defined in funcfile that determines the influence |
| 1110 |
|
of foreground. |
| 1111 |
|
The background coefficient is always (1-vname). |
| 1112 |
– |
Since the references are not resolved until runtime, the last |
| 1113 |
– |
definitions of the modifier id's will be used. |
| 1114 |
– |
This can result in modifier loops, which are detected by the |
| 1115 |
– |
renderer. |

It is also possible to give an expression instead of a straight |

variable name in a scene file, although such expressions should |

Functions (requiring parameters) |

must be given as names and not as expressions. |
