can you introduce an empty parking lot factor?
You don't need dummy map entries.
If you set the default model name to empty string and set the upperLimit on the random tag to be appropriately larger than the number of (real) entries in the model map, when there is no match in the model map the empty default model is exported.
In v0.7 the [tmsimulator_scenery_object][element] will no longer be exported if the model name is blank (to avoid the "..\..\..\..\objects\.tmb' not found"messages in the TM.log)
I had assumed that the default model was fail safe and would always exist , but that is no longer the case.
Maybe when Jeff is farther along with vehicle animation
the preview of Aerofly Life is very interesting.
It may make ObjectGen traffic redundant.
No indication yet of how the traffic is defined or how easy that will be for large areas.
The same issues of multiple lanes and intersections need to be addressed.
