CGTalk - MTOR: Shadow Aov

I have hit a problem and I dont know why I am not getting a shadow aov...
Looking at the sl code for the spot slim template there is a variable called __inShadowC. So when in the secondary display when I say color __inShadowC I get a blank aov. Any ideas?
I even tried plugging a color aov to the shadow color but it doesnt even seem to work.
There is a ratCollector, but I want to do it one shot using aovs rather than doing firing multiple renders.
Thanks in advance

If you're using MTOR 6.5, there should already be a color _shadow display channel in the Channel list in the globals; that's probably the one you'll want to use.

Also, remember that lights cannot modify AOVs. They can only be exported by surface shaders. Any of the slim shadingmodel_aov type templates (Matte, Delux etc.) should automatically be writing shadow values to the _shadow AOV.
