mia_material with alpha transparency

[jaidek]

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 the "transparenct propogates to alpha" and setting "Pass Custom Alpha Channel" isn't enough.:(

Here is a render of the "Glass (Thin Geometry) preset applied to a default poly sphere rendered on a black background (I adjusted the background color in Photoshop so you could see the sphere more clearly). The only thing altered was 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 "cuttout", 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,
