hello all GTA mod creaters. as a newbie in learning how to edit vehicles and skins
can someone please show me how to edit them
i am using Ultimate editor . i have extracted the Bmg file from txd of a car ..and i am editing it in ms paint. On the first sight i was like what the heck is this???

i am unable to understand the image..what the heck is drawn in them . and from where to start it. I am totally consfused.
i am talking about bmp images that are present in Txd and dff files inside the Gta3.img.
What is the logic behind that image names?? can we keep whatever name we like for bmp image or not..all bmp files are in parts..it is difficult to understand them....
Each car has its different bmp images in different style ...
I want to make a car like Suzuki SX4 how to do that???
