I tried, and still I just can use it with custom vehicles, and what I am trying to do is to use it for DEFAULT vehicles from the game, not custom onesI have exactly what you're looking for.
1) Visit my site... https://mm2silent.weebly.com/tutorials.html
2) Download the 2nd-last tutorial and follow its instructions.
3) If you want to see example of how its done, watch the first few minutes of the last tutorial on my site (called "How to Add Reflections to MM2 Screenshots").
Also I need to know where the default vehicle notepad is soo I can modify them, I dont want to use custom cars, It's just not mm2 with them in my opinion
