Human characters
I made this model using makehuman, that's free and open source software to create persons in 3D. I assume this is not a novelty, so you all know this software. Well, I made this girl in less than 20 minutes because it's easy to make a person using the software; anybody could help even being a complete beginner in 3D modelling. The most imortant: the ojects looks nice and after exporting them, the numer of edges are not that high. So, my question is: can this be useful for STK? If not, why?
Packages
Some months ago I sent a private message to a certain member of this forum and I asked him to post a new topic about this subject, but I changed my idea and I asked him to cancel the post, but now, I see some utility for my concept.
My main motivation for this idea is the fact that most part of my secret projects are based on past times. Let's see.
The number of tracks and charaters is increaing, what makes the game heavy and slow to download and to load. So, why not to allow the STK fan to download or to install only the tracks and characters he/she wants? I will be as clear as possible: can you pack the game giving us the opportunity to download or to install specific and thematic packages containing only the tracks and characters that we like?
For instance, we could chose between 1.Install all traks or 2.Install packages. The packages could be (the ugly names are just the first thing that came to my mind):
"Urban": Malao, the Asian metropolis; Tollway, etc.
"Sand and rocks": sand track, Hacienda, Mine,
"Mountain and Valleys": Snow mountain (Northern Refugee), Snow Tux Peak, Green Valley, Alpine, Bonive Banyard,
"Jungle and Mistery": Cocoa Temple, Cocoa Carnival, Zen Garden, Mansion,
"Sea Side": Absys, Paradiso Island, Lighthouse, Port (one of my own projects),
"Across the Universe": Enterprise, XR 591, ...
"Fun and Games": Minigolf, Las Dunas Stadium,
"Time Machine" (Past and futuristic histories).

I don"t know how complex this can be since the team of programmers is small, but, if this is not so difficult to do, we wold be very happy with this new feature. Forgive my ignorance about programming.
