The Re-Volt Hideout

How can I extract a vehicle's model for usage in RVGL, and then set the parameters on the vehicle along with installation of the antenna just like every other vehicle in Re-Volt?

To begin with, let's use Twisted Metal 2 (PS1) as an example. I have the ROM on my PC; how can I extract a vehicle model?

I think getting a model from a game requires different tools for different games, probably. I do not have experience with it myself. I think you might be able to get further if you already have a model. For example, from https://models.spriters-resource.com/. This site does not currently have the Twisted Medal 2 models, however.
