In this video, we are going to break down some awesome uses of Octane’s Dirt Node.

This video covers the same aging technique we demonstrated in our previous Arnold Curvature Map video found here.

Otoy’s Octane renderer is a fantastic GPU renderer that has gained popularity due to its incredible speed (if you have the hardware). Here is how they describe Octane on Otoys site:

“OctaneRender is the world’s first and fastest GPU-accelerated, unbiased, physically correct renderer. What does that mean? It means that Octane uses the graphics card in your computer to render photo-realistic images super fast. With Octane’s parallel compute capabilities, you can create stunning works in a fraction of the time.”

We plan on bringing you more useful videos covering more of Octane’s features, so be sure to keep your eyes peeled or subscribe to our YouTube Channel.

How do I choose my Octane Kernel?

I’ve gotten this question quite a few times so I figured I’d add it to this post. Octane has several “Kernels” or methods of calculating it’s renders. The most common is Path Tracing because it’s unbiased and often gets you the most physically realistic results. HOWEVER, I prefer to start every job using the Directlighting + GI Diffuse as my Kernel. This is not un-biased and therefore much faster than Path Tracing. If you set the bounces high enough on Spec, Glossy, and Diffuse you can sometimes get just as realistic results as full on Path Tracing but at a fraction of the render times (see image below). I’ll always start with Directlighting/GI Diffuse and then switch to full PT and see if the difference is significant enough to switch to full PT. Hope this helps!
