Mobile Shaders

Hi,

Please enlighten me, I have a simple scene set up for iOS as below, I'm light mapping so set all the shaders to mobile defuse so I could see the shadows as I set the lighting, but when baked and turning the light off the draw calls are 144 and as you can see I have Occlusion Culling set up and working, so I changed all the shaders to VertexLit and re-baked, this time the draw calls where 61.

The baked scene looks the same with both shaders but I can't see the lighting to set the scene when using VertexLit shaders, and its a bit of a pain to change them all from one to another to set the scene then change them again to bake.

Is there an easy solution, or has anyone got any tips.

Cheers.
