@Reyser how to edit .ymt files? they show only symbols in notepad.

@Reyser
Where can i find them on my game files? Exact location?

@Reyser

1. There is no carcols.met and carvariations.meta file to see the ids of tunning parts in Ferrari F50 folder. Only infernus.yft, hi.yft and ytd files and tunning files such as inf_wing_1.yft etc.

2. I don't think its id problem because when i open any tunning part which i renamed to e.g bullet_wing_1.yft it still says inf_wing_1.yft inside the Open IV model viewer.

3. I checked it with another car fusilade, changed all names accordingly and replaced them. Vehicle model worked but again tunning parts didn't work. Then i downloaded a replace car which replaces with fusilade, Corvette C7 2014 replaced the tunning files and the tunning parts worked. Then i opened the tunning parts given in Corvette folder in model viewer it showed fusilade_wing_1.yft both inside and outside of model viewer. So I think game doesn't recognize that tunning part because it says inf_wing_1.yft inside model viewer and think of it as infernus part? How can i change the name inside the model viewer?

4. Maybe i'm wrong & i'm confused please help!

@Reyser Hi I'm new to modding and need some help. I've read your tutorial and its great but it didn't answer my question.
I have a replace car Ferrari F50 which replaces with infernus but i've already replaced infernus with another car so I want to replace it with bullet. So i renamed infernus.yft, hi.yft and ytd in Ferrari F50 folder to bullet.yft, hi.yft and ytd and replaced orignal bullet files with them which worked. Ferrari F50 folder also has tunning parts for infernus so I again renamed them to bullet tunning parts and put them in bullet_mods.rpf but the tunning parts don't work. So how do i change infernus tunning parts to bullet tunning parts and make them work?
