hi
I'd like to change the file types listed in the geometry chooser…
currently the chooser pops up with a list of file types - with the option to select * as the filter, but I'd like to change this list - add a custom format…

where would I do this?

Does the file $HH/GEOio do this?

GEOio is how Houdini knows what tools to use to do conversions..
what I'm looking for is simply the list that Houdini uses to populate the file chooser…

Still, if you add the new filetype to GEOio it will show up in the list.
Maybe add a dummyDoNothing converter?
