The demo is available at http://render.otoy.com/downloads.php.
The installer assumes Poser Pro 2014, so you will need to copy the addons folder structure to your Poser 10 folder.
The MTL file exported from Poser probably does not contain the full path to the texturemap file, so Octane Standalone cannot find that file. If you copy the texturemaps used by the OBJ into the same folder as the OBJ then Octane Standalone should be able to load them correctly.My other issue is currently when I export out of Poser as an OBJ file, it does create an MTL file as well. But when load the OBJ into Octane, it would always ask me for the location of certain materials.
