So i put some red lines on my texture for skoda,its showing up in ytd but not showing in ytf file

Is this a model that you are making, or a model you are doing a retexture of? Some models may have 2 ytd files, named vehiclename.ytd and vehiclename_hi.ytd or vehiclename+hi.ytd. If the car has 2 texture (ytd) files, make sure that the livery file (likely something along the lines of sign) is changed in both of the vehicles files, and it is the primary file if the vehicle uses more than 1 texture. YFT files will not use secondary liveries even if those files are changed accordingly and correct.

I fixed it,it was because of some line on car
