Aamir, here is what I did, I produced seperate test kit for each nation, to be installed dependant on the state of the match, to do this, avoiding the black badge problem, you must go to "skin badges", delete the badge tim. for each nation and the patch l & r tim. this removes the badges from test kit, you then design your own team badge and put it on to each kit, ie. aus kit you would draw an aus badge on to the shirts, (this method does not affect the kits for one day cricket) and the blackness problem, it also allows you to desigh individual test kit. If you want to send me what you have done so far, feel free and I will look at it.
