Can someone tell me what exactly this files are needed for? :)

The .acc or .ac files are the 3D models actually loaded by Speed-Dreams.

I have only worked with them as part of track generation/creation, so this may not apply to cars.
The .acc files are 'compiled' or 'optimized' versions of the .ac files.
The .ac files are generated by sd2-trackgen. They can be edited with the AC3D software or they can be imported/exported into Blender (specific version?).
I think that the .acc files are generated from the .ac files using sd2-acc. I have never done this, I have always just used the .ac files as none of my tracks are ready for distribution.

There is a brief description here:


Hopefully some of the 3D moddelers out there will correct anything I got wrong.

I'll direct you to a post where I asked a very similar question:

Oh thanks.

But sometimes there are .acc~ or .ac~ or with ending .xxx~. What does that mean?
In some usermade things are they.

Hard to say without a specific example, but they are likely just older versions of the current ac/acc files.
