Hi there,

I'm working with a digital asset that I carried from another project and every time I create a new node, be it OBJ or SOP, it comes with a tab called Spare with about a hundred parameters and they all carry an expression bezier() in it. I tried creating another file, duplicating the HDA in a new location and installing it in the new blank file. After that I noticed the problem stopped, but after a few changes and maybe a couple saves and new interface controls created, it went back to creating that crazy tab and I can't figure out how to prevent it from doing so.

Any ideas on what I'm doing wrong?!

Thanks!

PS: I included a screenshot

There was a bug fixed in 10.0.313 where multiparms with internal names that contained digits would incorrectly create spare channels during a load. Perhaps that's what you're encountering?

hey there,

I just installed build 314 and I still get the same error… could it be that I need to cleanup my file somehow?

Cheers

If you click the parameter again, it will come up as the digit. See how the parameter is grayed out? That means you are looking at the expression, but because its a keyframe it just shows you bezier. You can tell its a keyframe because its a green color.

Maybe. You could put down a new instance, delete all the spare parameters via the gear menu in the parameter dialog pane, and then RMB on the instance and choose “Save Operator Type” to save the asset. This will probably only help if the asset shows “Save Spare Parameters” enabled in the Edit Type Properties dialog.

it's getting really weird now… I did everything like you said, Ondrej, cleaned up all the nodes in the HDA, saved it and started a new scene without loading the HDA. I then created a new geo node and it came with all the spare parameters as if the scene still had my HDA in it! Although I could see from the OTL Manager that it wasn't loaded.

I think I misunderstood. I thought instances of your asset were getting the spare parameters, not other nodes.

It sounds more like you saved some permanent defaults. Just delete all the spare parameters from the node in question and choose “Save as Permanent Defaults” from the gear menu in the parameter dialog. Alternatively, just delete the corresponding file from $HOME/houdini10.0/presets/.

What happens is that anything I create in that scene where I have my HDA comes with spare parameters. the spare parameters happen to coincide with attributes for some Null geo that I have as handles in my HDA. And even after I close that specific file where I'm editing the HDA and start a brand new file, everything I create comes with those same spare parameters even though there's no instance of my HDA in the scene and the digital asset is not even loaded. I have to quit Houdini and open it again to clear whatever is happening.

Can I trash the whole preferences? Would Houdini rebuild it?!

Yes, but I recommend renaming $HOME/houdini10.0 to something else in case there is anything saved in there that you'll want later.
