I actually like the mod if the creator will update it someday maybe think about adding PBR and more options for the engine, suspension and thats it i think.
i figure at this point we just need to update it ourselves, like with a lot of other broken mods like the dodge coronet
10/10 would create a non meshlap mod with the quality of a meshslap again (seriously the interior panels are just slabs of grey and you cant even add nos lol)
Some people live real lives, and don't have time to dedicate to modding, especially without any incentive.
Because the issues this mod has would require a ton of effort to fix (it's mostly a messy model and not the best Jbeam overall)
