I had this problem before with a zax shape and was able to get around that by rendering out the alpha channel of the zax shape and told KLF to look at the alpha mov. Now I am trying to use an obscuration layer with some keyed footage. Could not get it to work. So I rendered out the alpha from the key brought that into the comp and tell KLF to look at that layer and use the alpha as the obscuration type. Still does not work. it is either not there at all or there in full force and the obscuration layer has no effect. How can I get this to work before I go bald!??
