There are 3 variants of the SUV. It has 7 of its own addons, its own sounds.

The archive contains three bat files for clearing the Spintires: MudRunner cache:

1) Full cache clear (complete game settings reset).bat - a standard cache clear (deletes the SpinTires MudRunner folder located at \AppData\Roaming\), works from any location - just run it.

2) Cache clear (without resetting game settings).bat - clears only the game cache (does not touch user settings), works from any location - just run it.

3) Clear Media folder and cache.bat - my own creation: needs to be placed in the game folder; when run, it deletes the Media folder with all its contents and creates a clean Media folder + clears only the game cache (does not touch user settings).
Convenient for testing mods on a clean version of the game without having to configure the game each time.

All files operate automatically - just run and done :)

Brings the behavior of dirt in the game closer to reality.

Now, if you fly into the mud at full speed, respectively, mud splashes heavily stain the car, when slipping and driving through mud on high gear as well, but to a lesser extent, well, etc., depending on the selected speed mode.
The mud splashes themselves and their physics have been made more realistic, ridiculous lumps on wheels have been removed (thanks to Soul Reaver for that) and dry small hard lumps flying out from under the wheels, only slush has been left, its intensity has been increased at gears 1+ and higher.
Pollution on cars now has volume, which also adds realism.

I recommend using it with the following additions, it will greatly darken the visual effects of the new dirt:
SweetFX graphics improvement
Always the sun+Fog Reduction+Blue sky
Removing graphics noise

To work in multiplayer:
Do not install SweetFX. Use SpinTiresMod.exe with the original files in the game disabled.
PS. Many thanks for the help to Alexander Oboskalov.

Installation:
In case you don't like it, the archives of the game Media, MeshCache, TextureCache copy and save in a separate folder.
Copy files from the downloaded archive to the game archives, agreeing to a replacement.
In any unclear situation, we clean the cache.

Have a nice ride!

Got hooked on the game, decided to give it a try! I think it's pretty good.
Muddying the ground to original songs!
Enjoy your rides!
P.S. For those interested! There are many more songs (finished and in "drafts") For professional recording - https://money.yandex.ru/to/410015305698654

A recording of the developers' stream has leaked online, showing the first gameplay: SpinTires MudRunner - American Wilds!

Enjoy watching!

MeshConvert - a mesh editor for the Spintires format (those in MeshCache or _m)
MeshConvert saves ST game meshes for different game versions.
But not all meshes can be converted correctly; it is preferable to use the original X-meshes (with the .x file extension).
Also, MeshConvert can be used to edit the mesh XML.

Usage:
With this program, you can convert vehicles from the 03.03.16 version, specifically cached mesh files, to MudRunner.
Important! Don’t forget to then distribute all texture and model files into the necessary folders (which should be created beforehand): meshes go into the _m folder, and textures into the _t folder, accordingly. And provided the vehicle config in classes/trucks is correct, taking into account the new requirements for wheels and steering response. Also, the correct config for the wheels themselves in classes/wheels. The vehicle will appear in the game, though without drive shafts, as mentioned by the user above. Difficult? Possibly for some. But those familiar with the subject will figure it out.
How to use: unpack the downloaded executable into any folder. Double-click it, and in the window that appears, at the very bottom above the Load and Save buttons, select the path to the desired model (vehicle, addon), open the mesh, then click Load, and after that Save. A file with the _converted suffix will appear next to the model in the folder. This will be the finished mesh. Delete the old one, remove the suffix from the filename. That’s it.
Thanks for the instructions: Denis Korolev.

This program allows you to save and load game save files at any moment to prevent them from being overwritten by the subsequent save that occurs when exiting a session. For example, if you are worried about crossing a difficult bridge, you can exit the session as you approach the bridge, and the game will save (before the bridge). Then, run this .bat file, and it will save your position in another folder. In case of an unsuccessful crossing, you can load the previously saved position and try crossing the bridge again (or just give up on this doomed endeavor :))

The same applies to multiplayer, but after the player-server exits, all session participants must save the game.

I was motivated to write this program by team members getting stuck in multiplayer, after which they could no longer enter the game! Periodic saves help save the situation.

You can also completely delete all your saves.

Attention! To use this program, you need to disable Steam Cloud synchronization in Steam (cloud storage)!
To do this, open the Steam library, select Spintires: MudRunner from the list of games, right-click => Properties.
Select the Updates tab, and at the very bottom, uncheck the box for "Enable Steam Cloud synchronization." That’s it!

Installation:
Unpack the bat file anywhere and run it.

Technical information: The program copies saves to the folder C:\MudRunnerSaves\

Today the Spintires: MudRunner development team released a small update for the Spintires: MudRunner Editor.

Changelog:

- It is now possible to specify trailers in the truck selection dialog (necessary for creating a trailer without a tractor).
- The "Create terrain" menu now works again for the editor's root "prebuild" folder.

And as always, please share any suggestions and issues you find.
