If there is an object in the scene, for example a pair of glasses, by using a new feature in Poser 7 it is possible to make the object invisible at a certain point in the time line. With the glasses selected in the properties panel there is a invisible button with a “key icon” beside it. Clicking turns it green and the Reference Manuel explains a popup menu will appear. No such menus appears, however a morph dial appeasers  in the “Parameters" panel which should allow degrees of invisibility. Nothing like that happens but it does act like an on and off switch. However it does not animate on the time line. For example if you want to have the glasses disappear 50 frames into a 300 frame movie nothing will happened, the switch has no effect on the time line, it may as well not be there. Does anybody know what I am doing wrong?
