Octane Tutorial: Setting a exterior perspective through Rhino 5
Hello this tutorial will be going over the basics on setting up a exterior perspective in rhino. These settings include, camera settings, environment settings, and different passes.
The first step in setting up a octane perspective is obtaining a octane account and downloading the octane plugin for Rhino 5.
The next step is to open up the model you wish to render and finding a good view for your model. remember that it is always best to save your view in the named view tab so that you can return to that exact view.
The view that octane renders is the current view of your model in rhino. To open up octane use the command “OctaneRenderForRhino,” when the tab opens up you will notice that there are many different settings. In this tutorial we will be going over the basic settings for a successful render. The first category of settings is the camera settings. You want to make sure that it is set to a thin lens camera. One setting in this category that can be adjust easily for a dramatic affect is the aperture. This setting works the same as a camera. The larger the aperture the less depth of field the image will have. This is a good effect to use when focusing in on one specific aspect of your model.
The next category is environment. Octane uses the rhino settings for the sun location, however the power of the sun can be adjusted in the octane settings as well as the size of the sun/sharpness of the shadows. Two additional settings that should be adjusted are the Sky color and Sunset color. In the default settings both colors are set at very saturated tones of blue and orange.
Changing the colors to a more lighter shade will often help your renders look more realistic.
The next category of octane settings we will discuss is the film settings. This tab is where you can change the resolution of your render.
The last category of octane settings we will discuss is the passes category. to make post prepossessing the render easier it is useful to turn on the Material ID pass as well as the Ambient Occlusion pass. To make the sky empty you can also turn on the alpha channel.
We are now ready to start the render. Click open viewport and the rendering should begin.
The pass you will see when you open the view port is the beauty pass. This view is your raw render. In the lower left corner of the screen you will see “Samples/Pixel:” This number indicated the progress on your current render. However you do not need to wait for the render to be complete before saving. You can change the scale of the image by clicking the carrot next to the percentage numbers.
By scrolling through the pass tab, you can change between the two other passes that we turned on. The one above is the material ID pass. This pass is useful when post processing in photoshop, because it gives you the ability to select a single material on your render easily.
The other pass we turned on is Ambient Occlusion. This pass creates more dynamic shadows, that you can blend into the raw render when post processing.
Lastly click on the save button indicated above to safe the render. Note that you have to save each pass individually.
I hope you found this tutorial helpful!
