Scenes saved with PLE (limited) versions of Vue can’t be rendered on the RANCH, since they can only be rendered on the computer on which they were saved.
Cornucopia 3D protected content is supported with Vue 2015/2016
If you use Cornucopia 3D objects, plants or textures in your scenes, we recommend you use non copy-protected content. However, if you need to send scenes containing copy-protected elements to the RANCH, make sure to submit project with Vue 2015/2016, or protected content will not be rendered.
