I know thats why i'm posting in here.
Right this what is what I am doing.
1. Extracting the file from the cars wad
2. Opening it with GP4 genius (I can now see the wheel without textures in the preview panel)
3. Saving the file either as it's orginal name or a new name (makes no difference which.)
4. Try and open the file in 3Deditor (the lastest one) and get a message "File is locked, saved and export functions are disabled"
5. Try and import the file in zmodler, get the message "unable to read file: file may have an invalid header and/or is locked".
I'm not at home atm, so those error messages may not be 100% accuriate but it's something like that.
Doesn't make any difference if try and open in zmodler first.
Anyone any ideas?
