Hello,
I've just installed Octane 3.03 on houdini 15.5.480, the installation seems to be ok, all Octane functions seem to be present but the ipr doesn't show up.
The Mplay IPR in the Octane options does nothing either, it just opens a black Mplay window.
I am on a MacBook Pro where octane works fine on C4d.
Thx a lot for your help.
