Using Process Monitor, I saw (as expected) that the problem was that the AdskLicensingAgent was loading Qt platform plugins from Houdini: Ġ0:00:31 153MB WARNING | rendering with watermarks because of failed authorization:Ġ0:00:31 153MB | timeout before callback was called Reinstalling the application may fix this problem.Īvailable platform plugins are: minimal, offscreen, webgl, windows.Īfter AdskLicensingAgent crashed, the render would continue, but license authorization would fail: 00:00:00 148MB | authorizing with license manager: user. This application failed to start because no Qt platform plugin could be initialized. In this case, a Houdini command-line render with Arnold (HtoA) failed because the AdskLicensingAgent failed to start.



Or, “things that happen when you use single-user licensing on a render node” 😉
