Why is the exported model not displayed in the game in zmodeler 3.2.1 in ets 2 1.39?
The situation is like this, I like to play on ets 2 version 1.39, and recently started making mods. I downloaded the volvo for ets of this version and it really works on it and everything is fine, but I need to redo its model a little. For the sake of experimentation, I just decided to export this mod to the zmodeler 3.2.1 version, since my friend who is engaged in mods used to make mods on this version of zmodeler for ets 2 1.39 4 years ago. So, after exporting, I uploaded the mod to the game and after launching and logging into the game, going into the salon, the model does not load and the game crashes. What is the problem?

The question remains: why are you still playing on a version that is no longer supported by SCS?

Because the newer models are no longer compatible with the lower versions.
