Gradient Filling Line Drawings for Bump Maps


#1

I’m modeling the building in the picture,

and I have autocad line drawings of the bump map style ornament art as in the below picture.

I m looking for an easy way to create bump maps from such drawings with contours because I have dozens of similar drawings.

Is there any way to fill a closed line drawing with a gradient from center towards the contours? Or do you have any other recommendations?
