I plugged in my own tif texture and even a procedural checker, no crash :T

Argh! This is driving me crazy! I tried changing my prefs but this didn't help either. Do you think it could have something to do with the version (2012) or the fact that I'm using a student edition?

Shouldn't matter. It doesn't matter what you try to plug in, it crashes? Even if you saved your texture to a different format? Models have UVs?(weird put a shot in the dark lol)

Also check your crash log.

Tried a checker map and even that caused maya to kick the bucket. Yes, the models definitely have uvs. They're paint effect strokes that have been converted to polygons.
Where abouts can I find the crash log? I tried the path you gave Skalman in an earlier post ("C:\Users\Username\AppData\Local\Temp") but my machine doesn't have an AppData folder, not even when I search the entire machine.

Okay, some more little bits of information.
I've tried a few different tif textures, all make it crash when I connect the output value of the Luminance to the cutout_opacity of the Mia_Material_X.
Saving it to a different format eg. png doesn't help (for one thing it doesn't have an alpha channel) it still crashes anyway as soon as I connect it as above.
I've tried to save my file as a Maya Ascii and a Maya Binary but that didn't help either.

Ok to save everyone some time it is a bug. I did some QA work on it and the bug is fixed in 2014. Not sure about 2013 due to the fact I don't have access to that version.
But you don't have to go throught the whole process. In 2012 Maya doesn't like the output value of the luminace node being place into the cutout opacity of the mia shader.
You may have to settle for using just a tif in the cutout opacity.
It will render without crashing. I believe it does work in 2009.
Autodesk implemented QT in Maya 2011 so this may have been missed since it is a bit obscure for the QA to find this

Hi BldRnr, Okay that would explain why I'm having so much trouble. I'll have a shot at pointing my tif to the cutout opacity and see if I can get that working. As a side question why would this not be the way to still do it now rather than go through a reverse shader and then a luminance shader?

Okay this is my attempts at using the file to drive the cutout opacity. I basically just dragged my file (file1) onto the cutout_opacity setting and now I'm getting semi transparent leaves with faint black borders. What should I be doing to fix this?

For anyone who has the same sort of issues with the luminance node causing havoc in maya 2012 I have found a solution to the bug.
Autodesk released a hotfix package and that is one of the issues that it sorts out. (link below)

Hope this comes in handy.
