Its possible to rip the models from that game and slap them on a jbeam for BeamNG. That or make a custom Jbeam. Issues with credits, ripped models and so on though.
so how would i go do that wanna try and make a full pack of the trucks from ets2 custom sounds and all
Making mods for this game is much more difficult than it appears that you expect. Please read the Wiki to learn about how vehicles in beamng work and how they are made: https://wiki.beamng.com/Content_Creation
Making a mod for this game is kind of a pain in the ass when you don't know what you're doing. The easiest way would be to import the mesh from the game into Blender, export it as .dae & then use the T-Series jbeam as a base; this way you'll get a typical "Russian" mod that you do NOT want to use in this game. The best way (& hardest) is to learn how to properly model & code in jbeam, import the mesh into Blender (or a program of your chosing), separate all the meshes into smaller ones like cab, interior, doors, exhaust etc. Then, you'll need to make the jbeam from scratch, since the T-Series won't work for it.
You should first make Blender default cube to replace semi mesh, with that you would have at least some understanding required to start working on something like 3d model of some other game. In general, if you have trouble getting 3d model from some game to Blender, you need to do research how to achieve that step. No one is going to hold your hand and guide you trough this, it is nature of modding that you have to be able to come up with information by your own means, you need to be able to figure out things that are not very well documented, you will gain these skills by messing with game and doing silly things like putting basic cube in place of cab of T-series for example. Computer programming is same kind, you just have to sit hours and hours banging your head against the wall, trying to figure out missing piece of documentation to get some simplest thing achieved. I think that is most important thing to understand about modding. Modding could be done a lot easier, but it is not done so, which means not many have iron will needed to win obstacles and especially resourcefulness required to come up with information and ways. I would recommend making simple low poly mesh objects in Blender, texturing them and getting them into map as static objects first, that teaches few essentials, then go on and add upfit for T-series, at some point doing enough such things you will possess skills required to do a mesh slap. Most importantly though, you will need to learn skill of research, how to come up with information you need, like for example how to get model from game of your choice to Blender. At minimum you are looking more than 2 months if you can work few hours a day. When you have learned how it is done, you can do it in a day easily, but first time things are going to take long time.
