Surface shader looks different to standard?

I'm trying to make a basic surface shader, http://pastebin.com/Q8fgbUcZ , but I can't help notice that the result looks noticably different to the standard shader using the same parameters:



The differences are much more apparent when switching between them in the editor, but side-by-side you should be able to see a difference in the reflected color on the flat surface, lack of shadows on the bullet casing and on the edge of the breech.

In short.. why does this happen? What am I missing - maybe some extra pragma? I'd really rather not have to go through the standard shader's source and manually modify it.

 

For the shadows your problem must be the pragma line.
Try

Code (CSharp):

1. #pragma surface surf Standard fullforwardshadows

instead of

Code (CSharp):

1. #pragma surface surf Standard

For the reflected color I don't know.

 

Try changing:
_Metallic ("Metallic", Range(0, 1)) = 0
to
[Gamma] _Metallic ("Metallic", Range(0, 1)) = 0

 

Yep, that was it! Everything works great now. Thanks for the help
