What happened to the Mantra ROP preset menu? Instead of showing the presets menu it opens the visualizer menu, this is been there for some past versions of Houdini already, anyone else having this problem too?
Thursday, April 28, 2016 Houdini 15.0.461: Fixed a bug where the “Save Preset…” item in the parameter pane's gear icon menu was sometimes unclickable and instead opened the visualizer submenu.
