Info, thanks for slowing down for me. :>) It looks like neither one of us has math skills worth bragging over. We've taken this thread from some good posts on "Carrara Activity" down to splitting hairs over the upgrade cost of Motionbuilder. As entertaining as this is, should we continue or move on to something else? I've got one for you. What do you plug your Motionbuilder into for rendering your fbx files? I know that C3 does not do fbx, can Poser6 read fbx directly or work it through Shade? C4 has basic import support, but no export. wayne k guam usa
