Using the MAS system really makes keeping up with the car updates simple. S397 updated the cars to correct some bugs and a temperature issue that cropped up. So new versions & folders were created. What I have done is create a 3rd folder inside each of the BTCC Car brand folders and I have placed all the MAS files in that. for example:
BMW_330_2020\Version 1.00 Version 1.01 BMW_Mas folders. Then when an update occurs just copy the mass files from the _Mas folder to whatever the new version # is.(and then don't forget to DELETE the mas files from the older folder)
With this method, I had all your files right next to their new location and cutting & pasting was easy. All the skins showed up right away. Thanks!
