Mods Studio is an easy to use program. You just have to follow a few tips.

TIPS

1. Remember about texture sizes (dds). It must always be 256px / 64px for the thumbnail visible in the store. If instead of 64px will be 65px probably the skin will not work or we will have a game crash. The same applies to the jpg photo shown in the mod manager, it must be 276px / 162px. However, when it comes to truck textures, sizes may vary, but you must follow a certain rule. So for example for each truck will work texture 512px / 512px and its doubled value, i.e. 1024px / 1024px and again doubled, i.e. 2048px / 2048px and 4096px / 4096px. (I even made a skin with 8192px / 8192px texture but it is an extremely large texture so 4096 will be enough for quality lovers).
   
2. The manifest file is the file responsible only for the information displayed in the mod manager. These are information such as: mod name, mod thumbnail setting, mod description, version and game compatibility (i.e. is it version 1.36 or 1.35 etc.).
   
3. For semi-trailers, the principle of doubling is identical, except the texture of the semi-trailer is a rectangle, not a square, as in the case of trucks. Its values ​​start from 1024px / 512px as well as 2048px / 1024px and up 4096px / 2048px. In my opinion, it is best to work with 4096px / 2048px and the quality is also excellent.
   
4. To use mods studio you must install the .NET Framework in the version specified on the mods studio developer website. However, to use the .NET Framework and for everything to display correctly you need to install Visual studio and this information is often provided on the website when downloading the .NET Framework. Read exactly what you need to run a specific package / program.
   
5. If you are doing an advanced truck, you also need to set accessories. You will know what’s going on when you start your first project. The point is that advanced trucks have a accessories. For some of them you will find templates in the internet, for others, I don’t know because I have never looked for every temp. I do it so that I create a png square with dimensions 64px / 64px (of course, if you do 16/16 it will work too). Then I set the square with a color matching the skin of the truck and that’s it. I set it later in the mods studio for accessories and mark all the boxes on the right. If you do not have boxes, only information about entering the name of the element, it means that you do not have correctly installed all components such as net framework or visual studio.
   
6. The most important tip 😉 Everything must match. As I mentioned, one pixel difference is enough and it will crash. If you don’t believe me, do an experiment. Skin internal name – the point is that it is like the name that the program will set in most file names, textures, tobj files etc. It must be unique with each new mod/skin so that there are no conflicts. DON’T GIVE MORE THAN 10 CHARACTERS.
