Sometimes you’d see the splash screen, but then that would just disappear.ĮRROR: checkoutLicense: Failed to authorize license In this case, Maya 2019 would silently fail at startup. One of the strange thing about supporting Arnold at Autodesk is that you have to be a guru-level licensing expert on Autodesk licensing (not RLM, but Autodesk licensing). If you need more help, please send support your houdini.env file (or json package if that’s what you’re using) and the Houdini info from Show Details. If you have other renderers and plugins, I would remove all other plugins from HOUDINI_PATH, get HtoA working, and then put the other stuff back. You want to see the HtoA location at the start of HOUDINI_PATH
Third, check Help > About Houdini > Show Details You want something like this (PATH is for Windows only): # htoa config start Second, what’s your houdini.env look like? That is almost always because the environment (PATH and HOUDINI_PATH) is not set up correctly for HtoA and Houdini.įirst, how to do you start Houdini? Don’t double-click on a hip file, because the Houdini environment won’t be set up correctly. set QT_QPA_PLATFORM_PLUGIN_PATH=C:\Program Files (x86)\Common Files\Autodesk Shared\AdskLicensing\Current\AdskLicensingAgent\platforms The solution? Set QT_QPA_PLATFORM_PLUGIN_PATH to point to the AdskLicensingAgent\platforms folder. 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” 😉
