Camera View and Final Rendering --> Black screen

[Flange4789]

Details on my issue:

Software: Octane Render 2.06 Standalone (x64)
Octane Render for Blender 2.06 - 6.0 (x64)
Blender Octane Edition - 6.0 (2.71.5) (x64)

Problem: Start Octane Server, open up Blender Octane and use default scene (the cube and point light). Changing nothing, I simply select Viewport Shading as rendered and behold the grey cube floating in a blue sky + sun with white below horizon. Console displays "Octane: WARNING: only node-materials are supported" and "Octane: WARNING: only node-textures are supported". If I change the view point, the rendered view still works but if I select the Camera view (Numpad 0), the preview goes all black. If I try to render the scene, the render preview is also black.

Initially thinking that this is due to the unsupported Blender material, I delete the Lamp object (since this is a Blender Lamp), I unlink the default material since it is a Blender Material, and go into the Node editor. In the node editor, I delete "Material" and create a new basic material using a Material Output node and an Octane Diffuse Material node (deleting the Diffuse BSDF that Blender adds when creating a new material). Using the Octane environment defaults (Daylight etc.), the console continues to display "Octane: WARNING: only node-materials are supported" and "Octane: WARNING: only node-textures are supported" <-- this is confusing since the scene now only contains a cube with what I believe to be an "Octane" material, the Camera and the World. Once again the camera view and final rendering both produce a black screen.

The top of the 3D View also displays "No net GPUs" in the stats reported which is strange since I am able to, and have selected, CUDA + GeForce GTX Titan as the Compute Device in the User Preferences.

Computer Specs are:
Windows 7 Ultimate 64 bit
i7-3770K
16 GB RAM
GTX Titan (344.11 Driver)

I am very confused by the fact that the Rendered preview works but that the camera view and actual rendering do not. Any ideas on what I could be doing wrong are appreciated.

Just set the focal distance properly.
By default it is "0". You can either enable autofocus, choose the focus object, or set the distance manually.

That did it!

Many thanks, off to render some scenes now...
