So very Great Max!!

Just a possible suggestion:
Wonder if the script could be augmented to operate in both directions... It currently reads a bitmap to generate height... might it possible to analyze a surface and produce a height map.
That way, we could iterate between raster software and MOI to refine the surface iteratively in each, making adjustments each time.

For instance one might create a height map in say Photoshop, use your excellent script to bring it into MOI... use MOI to twist of otherwise modify the surface, and then have an auxiliary script write out the revised height map so it can be further tweaked back in Photoshop. With the various layer blending options in Photoshop, imagine the myriad of results that may not otherwise be practical or even discovered.

Just a thought... again great script.
I am sure that the entire community is equally as grateful as am I.

Thanks Max!!
