Round edges were significantly improved in Octane 3.05, and Otoy have indicated there are further improvements to be made. If you have specific issues with round edges in 3.05 or later, can you pls post them in the Octane Standalone 3.06 TEST 4 release thread so that Otoy have your bug report on the problem.Round edges are not working in Octane. And this is a big problem! I am rendering CAD files all the day, but it is often not possible to build round edges on object level.
Thanks
