hey poorfarmer25, thanks for the complement on the grizzly. I have a 3axis cnc router, I did it in 4 slices, each slice is 1.5" and the teeth I carved by hand. using deer antler.
Ok you may be getting the file in silo but it might be out of sight, you need to go in editors/option tab and open numerical editor, there you will see position x,y,z , click 0 for each and it should show up.
In sculptris I know it doesn't like to big a file so try decimating it to a lower file size. I use meshlab for that.And dont forget only quads or tri's in sculptris. also it depends a lot on your graphics card too. any probs just ask away. Graham
