Hello, glad to be here. This is my prime thread, and I would like to ask two basilar questions (I didn't found in search; perhaps wrong keyswords?). I work with Lightwave 9 (some would say "use something else", but since 10 years so far it is the only 3d app with which I feel confortable; tried many so far, but this adapts to me anyway, also 'cause I use building with splinepatch, which is a breeze in LW), and its meshsmoothing / subdivide methods aren't so fine (you know meshsmooting rounds badly the corners and "melts" the overall shape; one of the many cons of LW, alas), so I would know whether it is mandatory to have a very hi poly mesh, in order to use shapeways system. Second: I'm building negative shapes for ceramics molds' casting; thus, upon the resin model will be poured liquid gypsum/plaster. it is there a way to impermeabilize the model, or to coat it in order to optimally smooth the granulosity? Thank you for your time. Cheers.
