yes, all the meshes are referenced properly within the blueprints. IF I uncheck the ‘place on walls’ and check it to place anywhere, the object places in the world.
edit in: this is the tutorial I followed for making structural items: HOWTO: Add new structure variants - ARK: Survival Evolved - Unreal Engine Forums
But like i say, for placing objects on a wall, it gives me the green ‘go for it’ but doesn’t place anything. double checked to make sure I had everything in where it needs to be and I do according to that. They will work for anything but being placed on walls.
