OK so im making mesh pieces to build a store with, the shapes I am making in Daz Hexagon 2.5.1.79 saving them as OBJ's then taking them into Blender 2.73 64bit in order to convert them to dae files. uploading is fine etc and the shapes look how I want them too, my problem is when i upload them they have a "force field" around them which either raises me above the object so it looks like im standing on thin air or stops me from approaching it. Is there anything i should or shouldn't do when uploading? Cheers in advance for any help
