Exporter installed without any problems and worked without issue for me. Google Sketchup V 8.0.4811 - OctaneRender 1.025 beta2.52 x64.
I have used various Sketchup exporters in the past to get onto better render platforms, yours pretty much covers all the bases for me. Have yet to test the exporter to fullest of limits and still trying to get a feel for Octane but so far all good. Having good fun trying to get my blender model to export properly atm. Will give some more practical feedback when I've finished with current blender project and get to mess around again with Sketchup.
Hats off, good job.
