Tree matching / ignoring branches

Grasshopper
1

This is an issue which I’ve been running into a lot lately and have been working around it but need to solve this properly and am a bit stuck on it.

Have a look at the example below. I have 3 inputs which I combine into one tree where every input should be on it’s own branch. Each input gets a specific compound transformation.

Now, in some cases I don’t get any input on branch 0, 1 and/or 2. In those cases I would still like to match the input to the corresponding transformation and ignore the other ones. For example:

  • only 0 has input and gets transformation {0} applied to it, the other transformations are ignored.
  • only 1 has input and gets transformation {1} applied to it, the other transformations are ignored.
  • 0 and 2 have input and get transformation {0} and {2} applied to the respective input. Transformation {1} is being ignored.

What’s the best way to do this?

How about using Entwine instead along with the Filter Unmatched component (Treefrog)?

You should be using Entwine instead of Merge.

Entwine is what I was looking for, thanks @Rickson & @Joseph_Oster!
