I haven't started on it yet, or yes, i've made some notes, but not started on developing it....
It will include:
Over 50 different weapons
30 detailed backgrounds
Over 100 different misc. items
And many types of shoes, heads, suits etc...
And... A LIBRARY!!!
The library allows you to choose what objects to display, eg. a guns page and a suits page. It's going to fix most of the lag (all lag as long as the scene don't have very many objects)...
Also, when you click an object in MSC 2007, it will be aligned to front... Not in MSC III, there, you have to click the object, AND press space at the same time. Another nice feature is the rotate 45° feature, allowing you to rotate objects by clicking at the object and with the arrow keys (left & right) what way to rotate!
About the music, you can change between 3 different tracks (tracks not choosed yet) and also turn the music off. The only problem with the music player is that it will make the file size ALOT bigger.
Also, I will add a feature that allows you to clear your scene, so if you want to start over, it's soon alot easier...
I don't think I can say more right now....
Oh, and if you got some suggestions, comment! Please be as detailed as possible!
