Install this pack and you can dive in to Octane with tons of great materials/textures so you can hit the ground running. This pack includes over 500 C4D materials/textures to help you speed up your workflow and focus on being creative! OctaneRender has taken the world by storm and is setting the bar high for GPU renderers. I would recommend checking those out, since they are more optimized for current versions of Octane.
Note: this pack is now 5+ years old, and recent updates to Octane have been used in our newer Octane Texture Packs 1, 2 and 3 ( see here).
