Hey Guys, I have grabbed the Unity shaders of the website and am trying to edit the Standard Specular shader to be double sided with correct lighting calculations for the back side. Has anybody had any luck or done a similar thing ? I am aware that setting Cull Off enables back face shading but it doesn't have the correct lighting calculations. In theory i think I just have to apply the reverse normals (on the back face) and apply the lighting to the back faces but unsure how/where to do it as the Standard specular shader is so big with multiple passes. Anyways any help would be great!
