watch the video when you see the dog in the red material in the videothis is how i reduce the polygons in Quadshttp://ezbrush.blip.tv/file/2207070
for a lower polygon mesh i used cubical skinning then the new cubical mesh was smoothen then projected this allowed me to have lower and higher subdivision levels http://www.ezbrush.mediabakers.com/EZ-zdog-morph.zip
