I am new to the Shapeways experience, but trying to learn. I've managed to upload my first STL model and even fixed all my object thickness and manifold checks! I'm now trying to produce enough concept tests to eat up 25$ Very exciting. I'm also going over it again to find out exactly how thick it is in places, thanks to the excellent information on the forum here. 1mm cube, go! A bombardment of questions for my newness: What format should I export to if I want a colour print (my colours are in .jpg image maps)? How do I package it up after exporting for best use by Shapeways? I'm working with Blender 2.49 but I have a couple of other options I can transfer to and then export from if needed. What sort of resolution should the image maps be? Currently they are for CGI rendering, which means 2000x2000 (and up) pixels, and I suspect this is way too big. Should I downsample them, or can the Shapeways software do this? If I have a rather fat, roundish, creature, fitting in a 1" cube, is this too small for full colour sandstone? The materials detail says it's good for larger objects, but I'm not really clear on what is "large". Is sandstone the only option for colour prints at the moment? Is there a better option for small things in colour? Is there a script for Blender to compute the volume of a figure similar to the calculation Shapeways uses? I don't need it exactly the same, just to get a good idea when I'm modeling if I have gone too far or if I'm in the right area. Other than varnish or shelac or some other clear coat to protect the final product, is there other finishing needed for the colour sandstone? I'm pretty tolerant of a "natural texture" surface, but a solvent soak or the like may be beyond my resources.
