Re: Diffuse Color/Albedo Only Render Pass (Very limited...)

[Chris Harkins <charkocu(at)gmail.com>]

This method worked until I discovered one major flaw... Any material 
that has an incidence node will render out as the node piped into the 
angle perpendicular to the camera. For example, your simple incidence 
goes from red (inner) to blue (outer), but only the blue(outer) renders 
and the red(inner) is completely disregarded. This is incorrect as it is 
not the albedo color and its totally throwing off my comp. Evidently, 
the vector share hijacks the incidence node.

I'm really disappointed if its this hard to do something so very simple 
and necessary. There are plenty of packages like *censored* and 
*censored* that do it at the click of a button. Is there yet another 
jerry-rig we can perform to counter the last one to make an albedo pass? 
Or is this going to be one of those jobs where you spend unknown hours 
making a custom scene file just for one otherwise easy pass? Any insight 
and wisdom is greatly appreciated!
