It's the kind of idea that can make flight sim more compatible with ground type of simulation i would say.
Exactly where I'm coming from, so instead of the possibility of two or more separate development 'teams' with their ideas of what best suits their own individual requirements and bugger anyone else. We start at this very early stage to understand the requirements of each others genre and what we can DO to help each other by not making it difficult for them.
I've seen this far too often where people that want a functionality are more interested in getting their results and care nowt for the effects it has on others coming along later.
Looking at buildings we can start to develop a package of builds using models and textures that represent how we wish to use that building in the future, from walking into it, driving past it, driving through it, flying over it.... a new building, tired building, derelict building, destroyed building.. I'd suggest that once we've understood the format, textures needed it'll start to become for the artists involved as easy as shelling peas.
