Can we get these props available as still objects in the World Editor please? Would really help in detailing maps. Thanks
You should just be able to drop the .zip file with the object you want in your map files and they should show up in the editor. If you want to use props from other maps, that's what you would do, so you'd think the same would apply for these. Don't quote me, but it's worth a try?
You can open them up and remove the jbeam stuff leaving the .dae and textures I believe. They will then act like any other static object.
