I've run into this if I have 2 nodes with identical coordinates. If no beams are breaking, then it's probably that.
Hey, please double-check if the mesh name and the flexbody name in your jbeam files are matching up. You can also send us your files HERE so we can have a closer look.
Thanks for the reply. I started work on the suspension and once I updated the jbeam file the mesh was there 100%. No idea why. I will post code when I'm home later today. PS are there any good suspension tutorials out there? I have been trying to adapt some of the in game suspension and am having a hard time of it. PPS can anyone guess the car I'm modelling?
