Hi Tito and all,
Wow, I've been exploring a lot of other methods and engines including three.js but your solution with CopperLicht is by far the best I've come across for what I want to do and for what IT CAN DO! Amazing!
I too want to use Sketchup generated scenes and have tried and tested CopperCube with its CopperLicht JS engine and couldn't believe how straight foward, quick and easy it is to get it all up and running in the browser!
Thanks for the headsup and I'll probably be posting as I progress...
