Be patient guys ! juanjo is doing a great job with the houdini plugin.
sure it lacks some fancy features, but the plugin is reliable and stable.
Try to use octane in Maya / Unreal / Unity on real complex production scenario, and you will realise how lucky we are as houdini users.
The only integration that i find better is the C4D one, but Aoktar has start it few years sooner.
So keep pushing juanjo ! we have Faith in you man !

ps : regarding openGL
as otoy and arnold team are working together to integrate the standard surface shader inside octane,
https://autodesk.github.io/standard-surface/that could be interesting to chat with frederic servant to see, if you could do a common integration on the openGL preview inside Maya and Houdini. In other word having one comon agnostic standard surface inside Maya and Houdini , that get full openGL / hydra support and that could work both with octane and arnold ? that would divide the work and that would be stellar to be able to switch between Arnold and Octane without having to change anything.
