Hi All :-)
Please answer me. answer me.
I was studied about RimLighting with Unity5.
This is error message.
Shader error in 'Custom/Rim_light': constructors only defined for numeric base types at line 44 (on d3d11)
Compiling Vertex program]
and next is code(copied https://youtu.be/QRINA875mI8 ).
//
