Custom skins are not displayed in the showroom

I made a simple test skin (URD DTM2018), but it doesn't show in the showroom, I googled it and it didn't work for me (probably I didn't see it, but I read a few pages), I found that I can Create a new folder or replace put the skin on the vehicle, this way works for some cars, but some cars are just like that, only show one color, I saw this page https://www.racedepartment.com/threads /custom-skin-not-showing-on-car.211429/ , I see my alpha is white, but it still doesn't work, I also tried using png and it didn't work, also, I didn't change the filename

Thank you, I have solved the problem, but not for this reason, I found that my nvidia export settings should be set to bc2

Thanks! I was having issues with AC preview shots showing my custom skin almost completely black. I had it set to bc7 and changing it to bc2 solved all my issues.
