There is barely any info about these on BeamNG Documentation webpage. Where can I look up the default values of all the jbeam variables? The old wiki site says that they are taken from the jbeam_main lua file, but I cannnot find it anywhere either. Thanks for any help!
deformLimitExpansion from what i can find in my jbeam files is normally just "" or "1.1" (on occasion 1.2?), may have to adjust it for your usecase though.
Experimentally I figured out that these values are "FLT_MAX" by default. If deformLimitExpansion set for example to 3, it means that a beam can expand up to 300% of its initial length (gif attached).
