Need/Want to be able to do simple background swaps in PhotoShop - I have tried many many permutations of possible ways of getting the alpha channel (transparency) info - I either get a completely white or completely black alpha channel and R, G and B all empty too. There appears to be an option missing from Utility Map that might have been the key to this (see attached jpeg). I can get ObjectID AOV to work fine - totally stumped by opacity though - would appreciate some guidance or point me to a file so I can work out how it was done. Regards. Richy
