Issues with quad chassis

So, I began making a sports quad for beamng drive. I finished the frame, and I wanted to port it to beamng drive. After setting it up and creating the nodes/beams, I ported it. When I spawned it in, I had 3 problems with the frame. Heres how it looks in blender.


The First Problem was that is becomes flat when touching the ground.



The Second problem was that it would spawn with the beams and nodes visible which I couldn't make invisible.

The Third problem is that it spawns in upside down



So, can anyone help me with those 3 problems? I've tried everything I can think of, and none of it seems to sadly work.

 

So, I followed the tutorial, step by step, but then this happened.



Any other issues?

 

Do you have the code below at the start of your beams section?
Is you beam spring too high of the node weight?

{"beamPrecompression":1, "beamType":"|NORMAL", "beamLongBound":1.0, "beamShortBound":1.0},
{"beamSpring":501000,"beamDamp":200},
{"beamDeform":64500,"beamStrength":118000},

 

So, I put that in the correct section and the explosion became larger lol



Somethin else i'm doing wrong?

 

Can you pm the jbeam, so I can take a look at it?
