Is my Normal map supposed to look like this ?

[mattock]

Hi, Ive created my first normal map in zbrush 3.1, but when i apply it to my model in maya, the shading looks slighlty weird… almost like a negative.
looking at my normal map its really colourful, and when i see othe peoples normal maps they are mostly a purple colour. Ive attached my map
:rolleyes:
also when creating the map, Ive dropped down to the lowest subd level but should i switch morph target to the original mesh?
Thanks

Under NormalMap, make sure ‘Tangent’ is turned on.
