Also, if you like to stay informed of new updates for v10 or priors, including some add-on modules on 9.6, check the newsletters. http://www.thebest3d.com/dogwaffle/newsletter
In 9.6 there was a bug in the exporter for Wavefront OBJ format from 3D Designer. We mad ea patch for it. (now integrated in v10 of course). Well ok it wasn’t a bug, rather a lack of feature. But good to have if you create landscapes that you want to export to OBJ format for rendering in other 3D tools such as Carrara, Lightwave, and also in games. My preferred workflow metod is to use the eroded heightmap and have the terrain re-created in those other tools, which tends to rebuild the terrain seurface in a more optimal way, but your mileage may vary.
Also, if you’re in Windows 10, there’s an app included called 3D Builder. It can open and view the OBJ files coming from 3D Designer export. Very slick!
