In Octane, you can also render in accordance with 360, VR or Dome Mapping instead of just plain rendering. Let's look at the options now. At the end of this chapter we will explain how to render equirectangular type and view in 360 VR player.
Specifies the panoramic projection that should be used, with 3 options: Spherical Camera Lens, Cylindrical Camera Lens and Cube Map. Single-face cube map projections are available allowing users to render only one face of the cube. This is useful for animation overlays in stereo panorama renderings.
The horizontal field of view in degrees. This sets the x coordinate for horizontal field of view of the camera in the scene. This is ignored when cube mapping is used.
The vertical field of view in degrees. This sets the y coordinate for the vertical field of view of the camera in the scene. This is ignored when cube mapping is used.
If enabled, the panoramic camera is always oriented towards the horizon and the up-vector will stay in its default direction (vertical) at (0,1,0).
how to make 360o render Using equirectangular (sphere) setup
In this example we will take a 360 render and look at how it looks on the VR player. Then you can also see this render on Oculus, Vive or other devices if you like. You can also upload and edit YouTube videos with the method we will describe. We will not explain the Youtube part here, but you can find the source on the web. There is plenty.
You can download the scene here for tutorial.
01- Open the scene you downloaded. The light setups are ready. You can leave it as it is or make changes. Leave it as it is now.
02- Create one Octane Camera on the scene (LV Objects menu / Octane Camera). From the Object manager, select "Octane Camera Tag" and go to the "Panoramic" tab after making the Camera Type "Panoramic". Make the settings you see in the picture below.
03- Run Live Viewer. You will see a render as you see in the picture below. You can adjust the camera imager settings as desired. We have explained the details in the relevant part. What is important here is the Equirectangular view of your spherical camera. Although such a render seems straight to you, you will see that it is 360 degrees when we open it in VR player. So you have to design the scene with all the angles in mind. We recommend that you consider this warning for your future projects, even if it is not for the sample scene.
04- Now save the render output in png format. Our work with Octane is over for now. After that, we will look at how it looks 360 degrees in the render output with a VR player. For this, first download the free VR player from here.
After downloading the player, do the installation and run it. Drag and drop the image you have saved directly into the VR Player. You will get an image as below. As you can see, you can prepare the Equirectangular render output from Octane to any software that can display 360 views. If you want to do compositing, you can try Mettle Skybox plugin, which works on After Effects. It is default in version 2018 of Adobe Creative Cloud.
You can also load your renders into Oculus, Vive, phone VR gear or YouTube as soon as you have done with the output of your render as we mentioned at the beginning. We recommend you take a look at online tutorials for this.
