The Instance Position node can be used to sample an object instance location and use that data for texture projection purposes (figure 1).
Figure 1: The Instanced Position node connected to a Noise Texture node used to project randomize color across instances from an ORBXThe ORBX file format is the best way to transfer scene files from 3D Authoring software programs that use the Octane Plug-in such as Octane for Maya, Octane for Cinema 4D, or OctaneRender Standalone. This format is more efficient than FBX when working with Octane specific data as it provides a flexible, application independent format. ORBX is a container format that includes all animation data, models, textures etc. that is needed to transfer an Octane scene from one application to another. file
