It messes up your materials and flips the normals when you export, so just remember to put on Back face culling before you export and make sure the model has its normals the wrong way around then they will be right for Poser.....or just flip them in uvmapper, i find the the easiset thing to do as you need to fix the materials in there too...on the installation just create a folder called C4d or whatever and drop everything in there, once you have everything set up how you like, for example setting up your screen or plugins, then burn that folder to CD then if you ever need to install again you just drag that folder from the cd to the HD and put the SN in...the whole App structure is in the exe you see, no dll's and the like.......Steve
