Hello, thanks much to all looking at this; I also have issues on the same platform but different versions of houdini! I did models in H20.5 that that works fine but error out in H21.

I tried stashing right before the polysplits in H20.5 and they still error out being the first node in the graph in H21 (both on windows 11 on the same computer)

I only have this issue when doing non procedural modeling which I do a lot because even for procedural modeling I might do regular poly model on a piece that gets procedurally sized and placed!

But now I just know that when using these topology tools, I can’t have too much faith in the graph history and stash/cache at checkpoints.

I have lost time redoing large parts of models that I did in previous versions of houdini that I no longer have access to and they error out in current versions and it’s always the polysplit nodes that error! and though it might be a node up the chain causing it to not work, it doesn’t do much for me because once the split entries change, everything down the chain that depended on the previous topology breaks!

But using say maya, you’d have to delete history when modeling as well; However, this was one of the coolest things about Houdini for me to have that construction history there but oh well.

Understood Tomas, I'll try what you suggested here and do some more in depth checks to see if something else might be the issue. Thanks much!

hello again Tomas, it's working on 20.5.684. No errors. It's a large file with lots of models and when opened elsewhere tons of errors and all pointing to polysplit nodes.

In fact, all my files with huge modeling networks and lots of polysplits have errors in various houdini builds and only work well in the version they were created in and on the computer they were created on!

It all feels extremely fragile! I've created lots of models with semi procedural functionality where freezing does not make sense for some and I'm now very concerned!
