Sphere Light


The Sphere Light is basically a sphere object with a DiffuseAmount of diffusion, or the reflection of light photons at different angles from an uneven or granular surface. Used for dull, non-reflecting materials or mesh emitters. material and Texture Emission applied to it. This allows for additional lighting to be created without having to import additional plane geometry from another 3D application or source. A Sphere Light node can be merged with the existing scene using the Merge Octane and Nuke Geometry node (Figure 1). The Sphere Light can be found under the Lights category in the Octane Nodegraph Editor window.

The parameters for the Sphere Light are identical to the Texture or Black BodyAn opaque object that emits thermal radiation. In Octane, this is used to designate illumination properties for mesh emitters. Emission nodes. The parameters under the Transformation rollout allow for scene placement of the light source. The Sphere Light has an additional Object Layer rollout. Please refer to the Octane Standalone documentation for information related to these specific parameters.
