Exporting vehicle skin into mdl?

[DarkScientist_]

Hey,
I've made a vehicle skin for a TDM car (Ferrari 458 spider).
It works perfectly and I want to make it working with the simfphys vehicle add-on.

When you create a vehicle, it needs a link to a model, especially a mdl file.

So here is my question : how can I turn the custom skin I've made and the basic model of the vehicle into a model, which I will be able to set into simfphys?

Here is my skin :

Thanks for your help.
