Minecraft Immersive Railroading own trains?

I would like to create my own trains for a server project for the Minecraft mod Immersive Railroading. I only know that you can do this with Blender and that it will become a resource pack. I'm looking forward to answers

You already answered it yourself.

Make a resource pack and you have your own moves

But how to make the trains was the question

That was not the question. There was no question at all. Take a look at tutorials.

Können Sie vielleicht ein tutorial schicken finde keine bitteeeee😭
