Mat, something likely to come out in SkyMaxx Pro 2.2 is an API for other plugins to call (ie via XPLMSendMessageToPlugn) to create individual clouds at specific locations and sizes. If you guys get to the point where you're writing a plugin, and know where a thermal is and where exactly you'd like a cloud to be, PM me and we can discuss details. To set proper expectations, I'm still focused on getting SMP 2.1 out the door, and 2.2 is nothing more than an idea at this point. But this is something I want to expose as it lets weather engines / injectors have finer control than what is currently possible in X-Plane's existing API.
