Take a mesh that you wish to render as smooth. Do a least squares fit calculation using all of the points. I think I remember that this is done using three points in sequence - but however many - it defines the equation for a curve. All of the pixels on the surface of the mesh are then adjusted to match the average of all of the converging curves. You can be rendering a cross section of one facet and it will be curved, not faceted. This may or may not be exactly what FireFly is doing, but it is probably something close. You cannot export this, it is the renderer doing it. It also means that adding a lot of extra points just to make a mesh smooth, does not make it smoother, it makes for more calculations and a slower render time though. The speed of FireFly will depend on how dense the mesh is. Poorly coverted NURBS clothing and high poly figures, might take a while. We pick up Raytracing and a renderer that does near infinite smoothing. Not too shabby. Poser 5 hair. Building from an existing prop, a hair style can be made and saved to the library. The part that defines the actual Poser 5 hair appears to be based on calculations - not created mesh, so it looks to be internal to Poser 5 and not something you can export. If you are exporting from Poser to another program for rendering, it looks like you will have to use mesh based hair. Yep, I took a Vic scalp, grew some hair, saved it. It reopens in Poser 5 with the grown hair. Open the prop in MFM, and it is just the scalp - no hair verts. The hair is code in the library file. Shame on CL for offering something specific to Poser 5 that makes it special.
