Description
Currently we have the ability to replace the texture on an object with one from either a material browser or from an external file - however these new textures replace all maps from the original textures. It would be useful to be able to selectively NOT replace certain maps - most obviously the Normal map and Ambient Occlusion map, as this would allow for simple end-user customisation of assets without too much loss of fidelity. For example: A user applies the 'rock003' material browser map to a granite brick wall asset, ticks a 'preserve normals' and 'preserve AO' checkbox, and ends up with a wall that has a different colour and character but is still obviously a brick wall.
