• Check "Enable mods" and "Enable DLC".
• Check Show toolbar at the bottom of the panel.

• Before creating an object, you need to create a ".Ymap" map, (which will serve as a scene in which you can insert objects).
• Go to the first toolbar icon "new", then select "New Ymap File"
• A panel will appear. By clicking on the "map1.ymap" tab you can change the default name from "map1".
• To create an object, you need to click on the Ymap menu then select "new entity". An egg (default object) will appear.

• At the "archetype" level, replace the name of the object with the one you previously copied in Open IV.
• Delete the ".ydr" from the copied name Normally your object will replace the egg
