Hey all can someone help me please, I made a simple fuel tank to see if I could achieve something and learn to do the process, it shows up in the part panel where it should but its a blank square, if I try to connect it to something I get the two green connection dots but an empty space in between. Can someone please help me narrow it down to what step I mucked up, is it a model/mesh issue when I made it, did I do something wrong in Unity or I have got the .cfg wrong. Basically does anyone know what if any of those three steps would cause that. According to me Ive got it all right lol, but evidently not.
