I love grasshopper, and I have used it for almost 7 years now. It is an amazing tool. But the data trees have some really strange behaviors regarding empty branches, which have caused me countless hours of pain! :sweat_smile: Empty branches are not visible inside clusters The cluster works as expe…

The bug involving empty branches when editing a cluster has been fixed. This should be available in the next release of Rhino 8.30. Sorry for the delay!

+1 on this, thanks for bringing it up! :upside_down_face: Especially the clusters cause a particular headache. The really weird thing is, the clusters do not actually remove empty branches when in a GH-script. When in the cluster editing all would insinuate they are gone but they are still being pr…

I don’t know. I believe this is more a question for @DavidRutten et al.

Great list, thanks for bringing this up @Alexander_Radne [image] Alexander Radne: Empty branches are not visible inside clusters This one is particularly gnarly - haven’t really found a good workaround except placing dummy data in the empty branches.

There have been many topics about that. It’s a shame that this problem still stands. If it’s too complicated to fix I would like to have some component to put before / after the cluster that could do the workaround and recreate the tree structure for me. I’m not an expert on datatrees, clusters add …

I started a new thread this week that reports the same issues, with two GH examples: [image] Cluster tree bugs in R7 Grasshopper This must be a very old bug since it’s in R7. Beyond frustrating bangbang I have a tree where the last branch is empty. Outside the cluster,…

@dale bumping this. It’s an old, super annoying bug, please address this. Empty branches going into a block are removed, i have to populate all my empty branches with nulls before parsing to blocks and then removing them afterwards.

@sonderskovmathias - I’ve opened a ticket for this. Grasshopper bugs on empty branches : RH-91952 https://discourse.mcneel.com/t/i-love-grasshopper-but-not-the-bugs-on-empty-branches/181692 – Dale

@sonderskovmathias Would you have a simple example file (Rhino and GH file preferably) that shows this issue so that I can review it?
