Assetto corsa encrypted mods

[teirtlk]

Hello, a certain part of the modding community in assetto corsa we have been looking for a solution to the encryption of some mods by some modders, the thing is that without a specific plugin called shaders patch, we cannot use these cars, and if we try open with 3ds max something like the attached image comes out.
we are having a hard time with this because more and more mods come this way.
I hope you can help us it would be great
