Sorry, you cannot move objects in octane.That has to be done in your 3D app.
The only things movable in Octane are the Camera,the sun position, the direction of any IES lighting and any background HDRI lighting maps.
The correct work flow is as follows.
Model the scene in your 3D app. including applying materials or dummy materials to the models.Make sure you have UV mapped the mesh's correctly in the 3D app as well.Any lights you want to create in the scene should also be modelled in the 3D app.
Export the Scene to Octane.This will create a default Camera position.
Make sure the materials appear correctly in the scene once you are within Octane or adjust them using the Material picker or node tree on the LH Side.
Select the lighting mesh's in the scene you have created if you want them on and set them up as Black body emitters and adjust the power to suit or use I.E.S. lighting profiles if you need the interior lighting to be more accurate.
Adjust the Camera Position to suit including adjusting the Lens angle and any other camera settings that you need to apply.
Finally select the render kernel you require - Direct lighting (Faster) or Pathtracing (more Accurate) and finally the Resolution of the output.
Then sit back and let it cook till done and save out the tiff.
That's a rough guide.There are more settings than that but it should get you started
hope that helps a bit.
