[How to] fix disappearing of textures (partly)

I wanted to write short describe about the disappearing of textures but I wrote a little bit more. That’s why I created this topic to give a link to the subtopic: Disappearing textures - Possible fix?

I focused on vehicles but you can apply this solution for everything files of textures and object files.
Of course is more things to do, to completely fix disappearing of textures. Still work in progress. I will update if I found new solution.

Maybe you know any solutions?
I invite you to the discussion, it will certainly help many people!
