How can I create a 'wipe' transition effect?
hi, hope can help; i need create wipe effect, illustrate branch, sub-branches etc., 'growing' outwards trunk of tree. the tree, branch & background positions static on stage. the graphic elements created in photoshop, textured, detailed raster images, not vector shapes. i want 'reveal' branch, left (treetrunk end) right (twigs end). (ok, visually, not strictly 'growing', if wiped @ reasonable speed, works ok; tried in powerpoint) my first (& ideal) method use alpha channel shape masking branch, in statea reveal nothing of branch, stateb, revealing all, , fc tweening. ...but found alpha shape can't (?) changed, between states, on single object. another way use 'copy' of background, placed above branch graphic, , move left right, revealing branch underneath. but can't that, background isn't plain, textured, , anyway, there lots of other things going on in background (& foreground) @ same time branch wiping on. anyone got...
