So i modified a jbeam using the editor that comes with it, save the_body.jbeam filein the folder, but in-game is still not modified. tried restarting, doesnt work=/
It's old, buggy, and in my opinion shouldn't be included in the game. A workaround would be to copy the values from the left side and paste them to your jbeam manually.
you don't really need to, in blender you can find coordinates of vertices by selecting it and pressing n Also when i use BNE it's usually to adjust position of nodes and when I'm done i don't save it i just copy it and paste it into notepad++
well i just select the nodes i want to move, move them and hit refresh which updates the values on the left which i can then copy and paste into notepad++
