I'm hoping someone might have some insight on this. I downloaded the color relief shaded DEMs for the moon. I managed to get an acceptable sphere from the images, I may go back and try it again hoping for better results. Then I had a go at remapping the color shading to b/w, this definitely needs more work. Now for the good stuff, The spherical elevation map in color weighed in at 500MB, I converted it to b/w and down-sampled it to 6MB.(4000x2000px) I'm using Blender 2.6 I'm using a 100mm sphere for the model. In order to get the details from the map I ended up with 5.6 million faces. It isn't working so well with my whopping 2GB of ram...imagine that!. Is there another way to get the detail from the map with out having so many faces? ps. Anyone know which way is up?
