A while ago, we added many new props to the repository. Some were basically retextured and or resized versions of current props and some were entirely new props. Examples include things like various colorful trees that are present on some recent maps but not in any of the old maps, and some props that look like buildings. If you aren't familiar with what I'm talking about, you can check out the ancient-earth and alt-crystalline categories in the ozonex editor or you can load up the map Sacred Grove to see many of the new props being used.
I think it would be good to have a thread where people can suggest new prop ideas/new props that people could make to be added to the repo for all mappers to be able to use. So, if you have good reasonable ideas for some new props that you think should be added to the game, feel free to suggest them here and or share your new prop designs here.
