The 'Duplicate' layer makes multiple copies of the layers under it in real time.

It has a single parameter, "Index" which should be exported. This is the only ValueNode that will change from one copy to the next. This exported value can then be selected in the Children dialog and Connected to the parameter(s) in the layer under the duplicate dialog which should change in the copies.

The "Index" parameter has 3 sub-parameters, "From", "To", and "Step". The value of the exported "Index" parameter varies from the value of "From" to the value of "To" is steps of "Step".

"From" can be higher or lower than "To". It doesn't matter whether "Step" is positive or negative. The steps will be in the direction from "From" to "To".

Known Problems

  • Introduced in SVN r1267, this layer is kind of experimental and still undergoing changes.
  • Maybe it would be helpful to Auto-Export the Index parameter to give the user less work to do. It can always be renamed to something memorable later.
  • The layer doesn't seem to work well with PasteCanvas' parameters. Duplicating a PasteCanvas and linking the Index to its position or time offset doesn't have any effect.
  • It shouldn't be possible to Connect any ValueNode from the Children dialog to the Index param of a Duplicate layer, but it is.

Recently Fixed Problems (please test)

  • Cloning a duplicate layer and having one above the other (rather than having them each inside a disjoint PasteCanvas) causes Synfig to hang, since the same ValueNode will be used for the Index parameter in each of them. [ fixed in r1277 ]
  • It shouldn't be possible to Disconnect the Index param in the duplicate layer, but it is. [ fixed in r1278 ]
  • It shouldn't be possible to Convert the Index param from Duplicate to any other type, but it is. [ fixed in r1279 ]
  • It shouldn't be possible to Disconnect a Duplicate ValueNode using the Children dialog, but it is. [ fixed in r1280 ]
  • It shouldn't be possible to Convert a Duplicate ValueNode to any other type using the Children dialog, but it is. [fixed in r1281 ]
