i downloaded the elephant skull mesh and tried to use it for my map. it shows up in map maker but when i log in, i go to my map and the meshes arnt there. i tried to go to map maker and checked the "show collisions" box, moved them a little, saved several times, and reinstalled the meshes to my_objects and exports folder in the FH folder and yet the meshes won't appear in the real map. how do i make them appear?
