Is the any way to semplify a complex smooth model with much vertices

[theprodigy]

Hallow everybody, today I have download model of cyberdemon with a format to be honest I don't know it which is "Stereolithography format", and this model obviously is very complicated (30 megabyte) ..... I like it so much and I want to export It to a simplest possible number of vertices md3 or md2 format, and I usually work with blender 3d program ...... any idea?

I do not know much about 3D modelling in general, but you can use sculpturis, it got a function designed to reduce verticle count, while keeping the shape as much as possible, this do require some exporting and importing between programs, but sculpturis is designed for that too.

Concerning Blender md3 exporting.... I have actually never found a working plugin. So anyone got one for the taking?

I have succeed to reduce the vertices count model by the Blender's decimate modifier "here is a link of video if there's any one interest to know how http://www.blendernerd.com/reducing-vertices-tutorial/ " ........ and about md3 exporting ...... I'm using a good md3 exporter and importer for blender 2.45 and that is the same about md2 too, and I have an md3 exporter for blender 2.63 ..... if you interest to download it you just tell me and I will upload all of it.....
Finally I have a question for all. I'm working on a new 3d IMP and its need an animation, now I have bone it with blender 2.63, and when I tried to move some of bones to record the frames of moving, the current recorded frame became the default move and deletes all previous frame moves ..... What I have to do?
