Progress: February 23rd 2018 9:40am I am bored, so I found this 3d model of a shopping kart! The model is a royalty free one, so I know I can use it, and everything is separated for easy use! The only missing thing is textures, but I don't really need any. I will start with the jbeam later today! Progress: February 23rd 2018 10:00am Info.json finished, don't know why I did it second, but at least its done. Progress: February 23rd 2018 4:30pm Early jbeam shots. This is a test jbeam, and If it works I will modify it, or restart, this took 6 minutes to do Progress: February 23rd 2018 5:50pm The jbeam works! Now to make it not floppy and get the mesh in! Also I re did the jbeam. Progress: February 23rd 2018 6:25pm Paused Vs unpaused This still needs lots of work =\ Finished WIP Not Started _____________ 3D model 100% Jbeam 25% Wheel jbeam drivable? Anyone have suggestions on something extra to make on it, or do with it?
Suggestion : make a drivable version like @WillBeDaCoolest said. With go kart wheels, small engine... Also, I remember when @Asgalager was working on one like yours, but I guess he abandoned it...
Might be royalty free but should still include credits. Could be a cool prop if done right so good luck.
I will put it there! --- Post updated --- Yes I will try that after I get it to work as an extra, then it will be a vehicle XD
I'm not sure what those are I'm new to this, I'm just testing it right now so I know what i'm doing in the future.
For every square in the Jbeam, cross the two corners like this: (I made a small example at the bottom)
O Oh ok. As I said before, this is kind of just a test jbeam so once I get it to work, I know how to do it again.
It won't work without the cross-bracing beams, it will most likely just collapse as soon as it spawns.
Yeah, but I want to know how to get the jbeam to work in general. I have never successfully created my own jbeam before. I also don't know how to make the mesh appear (yet)
That would be the flexbodies section of the Jbeam file. The wiki has a lot of great tutorials on this stuff.
o Oh I know, I just suck at looking in the right place. --- Post updated --- i did it! oof and i broke it editing it it wond spawn now --- Post updated --- Can someone help me?

First you need to read and understand whole of this: https://wiki.beamng.com/JBeam_Introduction From there you can then look this page that is more of practical tips: https://wiki.beamng.com/Construction_Guide After that doing this should be piece of cake and very helpful to understand how to put all that info together: https://wiki.beamng.com/Introduction_to_Vehicle_Creation Update: You will get then into trouble at some point and this helps then: https://wiki.beamng.com/Vehicle_Modding_Common_Problems When mastered all that, then this tells how to get really good: https://wiki.beamng.com/Vehicle_Creation_Workflow This is then home page for any vehicle modder, remember to scroll down as there are more stuff, different stuff than at beginning of the page: https://wiki.beamng.com/Vehicle_Creation_Megapage That all would be ABC of creating a vehicle in BeamNG, kind of path which gives knowledge and skills to create anything you want. Except there is some bits missing from engines and stuff, but features of game are so vast, that there is probably always something missing.
Its not completly stiff yet, but I re did the jbeam and! Ta Da! @fufsgfen is this right? I read the wiki and I think its correct!
If it holds together and you can lift it with node grabber, it certainly should do. Of course you need to then test how much it weights with weight pad and ram it with a covet to see that it behaves right, but what I can see (and what little I understand) it looks to be right, good job!
Weight tuning can be bit annoying, remember that number of beams connecting a node effects how light node can be. More beams connecting and it might become unstable so node weight needs to be increased. beamDeform and beamStrength are how strong your beam cage is, beam spring is how easily beam will bend/flex and it is different from beamDeform as deform is amount of force needed to permanently bend, while spring affects how easy it is to bend but not permanently. So tuning weight can take time and you might want to do changes to structure while doing that to meet your weight goal.
