Preloading WebGL objects

Hello,

We're building WebGL objects in Unity that we're putting in our courseware. They range in size from 20-70MB. When uploaded to the LMS and launched, the user has to wait 5-15 seconds for the WebGL object to load. I've taken a look at the "How Course Content Is Preloaded" page, but it doesn't mention preloading of WebGL objects.

Does anyone know of a way to trick the system into preloading the WebGL content so when the user gets to the page with the object, it presents immediately?

Thanks,

Tony
