Question by MaT227 · Oct 10, 2014 at 05:43 AM · shader lighting forward surface shader deferred

Unity Surface Shader - Deferred lighting viewDir and lightDir

I would like to know if this is possible to have access or maybe calculate the viewDir and lightDir inside half4 Lighting_PrePass (SurfaceOutput s, half4 light);

Concerning viewDir, I would like to avoid adding it in the SurfaceOutput.

Is it possible to access viewDir and lightDir in deferred lighting ?
Thank you.
