This is a fairly straightforward extension of the previous shader. It adds support for point lights and multiple light sources. Unfortunately we have 2 diverging paths for lighting that makes things difficult to be 100% the same in either program. As far as i know, i can only access the position data in Maya for the point light, and not the falloff or brightness, so i used the light color alpha to determine brightness and added a custom falloff attribute.
In terms of Unity, lighting is done in multiple passes, generally one per light as far as i can tell. This may be behind some of the draw call woes i've dealt with in the past with Unity...perhaps i should work on lightmap support for these at some point to reduce the draw calls.
In any case, both examples are available for download.
