The file was originally named in Portuguese and, by mistake, I uploaded the wrong folder containing the file with the original name instead of the renamed, but this has been working for three years. But, what exactly is the point? Do you want a file in English? Note please, that it will not replace the file with the wrong name automatically, since the texture with the wrong name (in Portuguese) is the one that was attributed to the object that it should cover.
Here are the files named in English:
If you want to insert the file with an English name, you need to download the .blend file as well you must have knowledge of
Blender to perform the necessary operations, which are easy for anyone who has a bit of practice with that software.
As far I know, the uploaded .blend file to the addons website doesn't contain the blue truck, since it was made later.
So, in this case, the textures above will be totally useless for you.
In other words: keep the files as they are.
