How to convert car model to GTA V?

[Nekar]

Hi everyone. I want to convert a car I modeled to GTA V.

Is there somewhere a list of software that I need to do this?
Is it possible to do this without Z-Modeler?
What are my options?

Thanks,

@TobsiCred it is a model I designed and created myself. I have it in .obj format. Thanks. German is more understandable than French for me. But it seems from the start i definitely need Z-Modeler.

Thanks. I'll have to wait until Christmas for Z-Modeler...
