So the 2018.3 roadmap states that SpeedTree 8 models are supported but the one I've just purchased on the SpeedTree site does not appear to work. I'm assuming that none of them work so is this a SpeedTree problem or a Unity one? Do they work and if not why does it state so on the roadmap?? I get the following error message on import: "SpeedTree file does not contain run-time data. Be sure to re-save it using the Unity-specific version of the SpeedTree Modeler". Cheers!
