Shader question about Bump Mapping

Unity Engine

So, if the iphone can’t do bump mapping, why is the bump specular shader included in the iphone build?

Specular does work though right? I see specular on the ship in the Star Troopers demo.

Also, does vertex color on a mesh work on iphone? I’m new to Unity, and don’t see any documentation about it. Does it just work automatically?

Thanks for any info on the subject.

Vertex color works on the iPhone. Download this example to see it in action.

The specular highlights you see in the Star Trooper example are vertex lit.

Unsupported shaders were included in the iPhone version of Unity to make porting of existing Unity projects easier.
