Hello All,
I have been playing around a bit with the mia_material in Maya 7.0 and it is great! However, I cannot seem to get transparent objects to create a proper alpha. It seems that setting "transparency propogates to alpha" and "Pass Custom Alpha Channel" isn't enough.:sad:
Here is a render of the "Glass (Thin Geometry)" preset applied to a default poly sphere and rendered on a black background (I adjusted the background color in Photoshop so you all could see the sphere more clearly). The only thing altered was enabling the propogate to alpha setting. I also have Pass Custom Alpha Channel enabled. Here is what I get:

Its like the refractions transparency information isn't being taken into account. However, if I connect the outTransparency of the mia_material to a reverse node, then reconnect it to "cutout", I get something that is closer to a usable alpha. Just seems to be a sloppy workaround. Anyone have any suggestions or solutions to this issue?
Thanks,
