What's wrong in this jbeam files?

There are way too many nodes. That jbeam would need to have infinetely small nodeweights which the game cannot handle. Even if it could load the jbeam it would be extremely sloppy and would require several thousand beams just to reinforce it.

Look at something like the Covet front bumper, it has under 20 nodes. Your N/B shouldn't be anything over 40 otherwise you will spend several weeks reinforcing it and making it behave realistically.

 

That program makes jbeam look a lot easier.
I didn't know there was software for that.
I thought you had to do everything by coding in the .jbeam file.
