Hello There is a somewhat long way around that problem, I have tried to do the same thing but dint work the way i wanted to. If you are familiar with outodeks maya then an option might be to use the Sketchup plugin for maya to import the models in to maya then use the org exporter in maya to export your model to your hard drive for uploading. Maya will create the collision file as it will also create material and mesh files. You might need to reverse Face normals on your model in maya or your object will turn invisible because Sketchup only creates planes "one-sided visual suvices"
Maybe it helps you a bit. Best regards George. -- http://groups.google.com/group/realxtend http://www.realxtend.org
