Sorry for my lack of understanding, i'll try to explain what my problem is.
I Open up SparkIV, opened up vehicles.img, imported the police.wtd file from Unr3al's, edit the police.wtd file from unr3al. At this point i can't find any "Police_sign_1(2/3).DDS"
And "Disabled Angel" is telling me to import unr3al's .wtd file, enter the file, export the police_sign_1. Then import the original car's .wtd back into unr3al's police.wtd. Am i right? Or could someone some instructions that i can understand. Any help will be appreciated.
