I have made my level in ZE, but when i go to play it, none of the objects or command posts show up.
Please do not post a help topic like this again. When someone says that "something went wrong", everyone else will have no idea what you did, or what happened. Start by saying what exactly you did. A complete step-by-step.
Make sure you added all the .msh and .odfs (found in the assets/shippedworlds) for the objects you used into your Wolds folder for your map. You need the raw files to munge, not just the ZE placement data to make a map.
