i make extensive use of the visibility keys to animate transparancy in Max (flying logo’s, text, etc.). since i’ve switched to mental ray for rendering, i have noticed that mental ray treats a visibility key as either on (for a value of ‘1’) or off (any value between ‘0’ and ‘0.99’). i’ve tried a handfull of different key controllers with no luck.
anyone else have this issue? any solutions, workarounds, or tricks?
for now i’ve been animating opacity on individual materials, but this causes issues of its own (reflections, speculars on transparent objects, etc.) and adds crunch time to tight deadlines (animating individual textures on complex/multiple material objects).
thanks in advance for any help!
