The maps need to be using 'world space normals', if you want to do it with entity color. I think the demo with the statue Rob posted some time ago, used that technique.
The one in my example uses 'local space normal maps', which means the color for each pixel in the map is calculated as an offset compared to the normal of the triangle it is applied to.
I don't know if these are the right names for it :)
