AmLachDesigns,
I have not tried the decimate modifier, I was not aware that it only removed from non "busy" areas. I will give that a try.
The sphere is hollow now. The wall thickness is 4mm for now, only because I didn't know how deep some of the craters were.
I am aware of the limits for file size and face count, that's kinda why I was inquiring.
I still need to nail some of the basics tho... I'm not even sure I have the displacement map "normal" facing the correct way-and I still am not sure which way is up. The image work takes some time due to file size, so i was trying to get a better handle on the blender steps before I commit to full size. I'm wondering if there is some way to average the data. I know at some point there is no reason to use a smaller face(more faces total) because you will already be exceeding the printers resolution.
My basic sphere is around 25k faces(then subdivided) and I'm using a grayscale image with the displacement modifier to create the topology. The conversion from color to grayscale is somewhat iffy too. photoshop only remaps in color steps( 6 sliders) so I set 50% gray to approx. 0ft elevation(which is not necessarily correct) and try to get an even blend around it.

I'll let you know what happens with the decimate modifier. I was planning on FCS. I had considered using the displacement map as an image texture. I think I'd rather have less detail and no image on it...if i can get there from here.
Thanks for the input both of you.

ps: Shapeways, if you're listening, and have considered printing in cheese...this would be a great thing to print in cheese. :laughing: just sayin'
