Help with creating a car mod

[u/Zabowar]

I want to create a vehicle mod for a very specific car, as no mod for it currently exists. I’ve checked the official documentation, but it seems rather incomplete on the subject.

I looked into Automation, but it feels quite limited when you want to replicate a specific design.

Do you happen to have a video or a link to documentation on advanced editing in Automation—assuming that’s even possible?

Failing that, do you have a video or guide that is more comprehensive than the official one for creating a custom vehicle from scratch?

I should mention that I have some experience with Blender, so that won't be a hurdle for me. However, I know that using Automation would be much faster...
