[Request] HELP! WSC 1970 rFactor

Hello, I ask for help with this problem that arose, I reinstalled this impressive Mod taking advantage of the quarantine and I realized that there are missing cars that ran in the WSC 1970, and the cars are, but the paintings are missing. So I started to paint after Exporting the Skins with the gMotor MAS, but then when I enter the game the car is not seen, I tried to put it as it is in the image of the folder, then I put it inside the MAS file to the DDS, but it throws me a GMT error, and I don't understand how that file is made, somebody knows please! I have the time and dedication to finish the missing cars of this Mod and I would like to share it with all of you, I am very detailed with the little details and I want to do a job well done to share and that all the cars that ran that season are there. I hope they help me please, while I wait for the help I will continue painting the other cars, which I hired by posting the Skins here, but until I can put them inside the rFactor and see them not really how they will look. Sorry for my English, but I use the google translator! Greetings from Argentina.

Good evening, you just want to insert a skin in rfactor?it's been a long time since I'm not playing mas I can help you, but you talk about g motor but, at the base you just have to put the file dds in the folder that corresponds to the car, we will find the solution together.

bonjour,
si j ai bien compris vous n arrivé plus a voir vos skins?
le plus simple prenez votre fichier dds et le mettre dans le dossier suivant.
