by | Jun 7, 2021 | Uncategorized | 0 comments

Want to learn Octane?

Back when CPU rendering was the norm, rendering was a slow and lengthy process. It took hours, days, even weeks, to render a scene. Otoy’s OctaneRender was one of the first to shift rendering to the Graphics Processing Unit or GPU, allowing the software to render images in minutes.

Today, Octane is one of the best render engines in the industry. And here below, you learn all about OctaneRender and discover its many features.

What is OctaneRender? 

OctaneRender is a GPU render engine developed by the software company, Otoy. This render engine was the first commercially available unbiased raytracer that fully utilizes GPU, which cuts rendering time significantly. It also lets users update scenes in real-time. 

According to Otoy, OctaneRender is the world’s fastest and first physically correct renderer, which means the software has a way of calculating the final rendered image to achieve the highest level of design, quality, and realism. This render engine is often used in movies, video games, and architectural designs for special effects and design visualization. 

OctaneRender key features

Seamless integration: One of the reasons why OctaneRender is so widely used in the animation and visual effects industry is that it can integrate seamlessly into a wide range of content creation and 3D animation applications. It’s compatible with 3DS MAX, Maya, Cinema 4D, Houdini, Lightwave, and Modo, just to name a few. 

Flexible: Octane is available for Nuke and CAD applications. The renderer lets compositors transfer scenes between applications easier compared to other rendering engines. That’s because Octane’s ORBX format could decode videos entirely in JavaScript on standard browsers without using third-party applications, plugins, or extensions.

Real-time responsiveness: OctaneRender lets compositors modify a scene in real-time. It boasts one of the most responsive render preview systems in the market. Because Octane is an unbiased renderer, it’s easy for beginners to learn and use Octane materials, lighting, and cameras, to create real-world settings. 

Should I learn Octane?

Should you learn Octane? Yes, you should! It’s one of the most widely used render engines in the VFX and animation industry. To stay competitive as an animator, you should master industry-standard software applications like Octane.

Fastest GPU rendering

Octane Render is powered by NVIDIA CUDA™ technology in all Mediaworkstations, ensuring fast GPU rendering to your desktop workflow. It provides almost absolute scaling in performance. Generally, a simple scene takes about several minutes to render. With Octane, it could cut through simple scenes within seconds, which shortens the rendering process significantly.

Real-time preview

Octane’s LiveViewer lets compositors modify a scene in near real-time and achieve photo-realistic results. Each time an attribute is changed in a scene, Octane’s Interactive Preview Region (IPR) updates the scene almost instantly. Depending on the plugin you’re using, Octane lets you access material selection, focus point selection, and AOV/render layer preview quickly. 

Ideal for compositing

Octane is available as a plugin for Nuke. Using Octane on Nuke, compositors could implement deep pixel rendering using the latest compositing toolsets. Combine these exclusive tools with the speed and power of GPU rendering, and you’ve got an effective compositing solution for visual effects. It’s a terrific software to use on scenes that require smoke, dust, flames, and other effects. 

A full materials library 

The application comes with a huge library of materials that you can access through the OctaneRender LiveDB. Because Octane is an unbiased render engine, beginners will have an easier time grasping the logic of the said materials. It also supports a full material baking paradigm for optimal real-time creation. 

Node-based workflow

OctaneRender provides a node-based workflow for VFX-quality shading and lighting. Nodes are used to manage almost all aspects of the applications, and as well as the Octane plugin environments for materials. Although nodal workflows aren’t beginner-friendly, they are efficient, especially when using gradients and texture files that require only one node to control multiple outputs.

A massive ecosystem

OctaneRender plays well with other 3D animation applications. Depending on the package, Octane subscriptions come with access to plugins for Cinema 4D, Maya, or Houdini. Some packages come with OctaneRender for After Effects and OctaneRender for Nuke. You have the option to choose OctaneRender Cloud (ORC) to leverage the power of GPUs in the cloud.

Being one of the most popular render engines in the business, Octane has a massive online community consisting of thousands of new and veteran artists. Whether you need a quick walkthrough or troubleshooting, the Octane community will provide all the help you need to use the render engine properly.

How do you use OctaneRender?

Octane can be used for lighting and compositing. Thankfully, Otoy’s forums provide a bevy of free resources for beginners. It’s possible to use OctaneRender even with zero experience. You can learn as you go along. 

Lighting in Octane

By default, an omnipresent ambient light illuminates the scene. The light does not provide attributes for control, but environment light can be added to the scene. You can find the lights in the “Objects” menu of the application’s dialog window. The menu outlines the list of lights that Octane offers, including:

  • Octane Daylight
  • Octane Planetary
  • Octane Area light
  • Octane Targeted Area light
  • Octane Ies Light

There are three types of environment light in Octane. These are:

  • Texture Environment
  • HDRI Environment
  • Octane Daylight

Texture environment applies ambient lighting that can be adjusted with a Power setting. You’ll use the additional Octane node (RGB Spectrum) connected to the Texture parameter to change the light’s color. 

The HDRI environment is a light that’s similar to the Texture Environment light, but it features an ImageTexture node connected to the Texture parameter. This way, the HDRI images could be imported to use as lighting information. 

Octane daylight could come in the form of a sky to provide ambient illumination or in the form of the sun to provide a directional light source in a scene. Direct lights in Octane are: Area Light, Targeted Area Light, and IES Light. 

Materials in Octane

Materials could be accessed and created from the “Materials Menu” found in the Octane Dialog box. Here are the materials available on Octane:

Diffuse: applied to simulate non-reflective materials or light-emitting surfaces

Glossy: applied to simulate shiny materials like metals 

Specular: applied to simulate transparent materials like water or glass 

Metallic: applied to simulate metallic shine (gold, silver, copper) with physically correct IOR

Blend: applied to create multi-mix materials

Toon: a type of cartoon shader that works for specific toon lights

Mix: used to combine two types of materials

Portal: optimizes the rendering of light sources by finding important light sources in the scene

Accessing pre-made materials on Octane

Octane comes with an online library of premade materials called LiveDB. You can access LiveDB on the Materials menu. Just choose the materials you need and download them. Exploring the premade materials library is a great way to train yourself to be used to the application’s material system. You can use the materials for your projects or download the essential materials to see how they are made. 

Choosing materials on Octane

You can access the Materials in Octane using the Live Viewer window. Once you’ve chosen the material, it can be previewed in Cinema 4D’s material editor window. Double click the material, and you will get to the material creation window.

You can also access the materials via the cinema 4D material window. From the window, you can create the material from shader C4doctane.

You can also use the Octane Node Editor to access the materials. Go to the Materials menu in the LV window and choose Octane Node Editor.

Creating materials via the Node Editor

Open the Node Editor, then drag and drop the Octane Material button from the left menu to the middle area. Select the node, then the Basic option to the right side, and create the material you want from the Material type section. 

Creating Materials shortcuts

The simplest way to create a materials shortcut is to select the “Customize Commands” from the Cinema 4D window menu  (Shift + F12).

It opens a window that lets you create a new Palette right beside “Edit Palettes.” Choose your desired palette window size, then set it. A list of commands will appear and begin automatically. You can drag and drop the materials from this area to the opening palette, and your shortcuts are done.

Texture in Octane

Texture is crucial in creating realistic materials regardless if you’re working on an image or procedural. And to simulate real-world texture, you need to study how light behaves in different surfaces and conditions. You have to analyze reference images carefully to determine what other surfaces look like in different lighting conditions. You’ll need to experiment with various texture tools to determine the look that you want. Thankfully, Octane Render offers a diverse selection of texture tools.
