Unfortunately armor modifications [i.e. changing the color] Won't work if you have the armor on.

So if you change a Rapid binders color to White from it's default black, even if it's within the file, it'll instantly crash you when you put on the Rapid.

So sad, i just think it can change the armor paint. Cause I see the pic of black fox binder in the forum ^^!.
Thankyou so much.
