Texture Environment

The Texture environment affects the illumination and color of the environment. It can be used to add a HDRIAn image which presents more than 8 bit per color channel unlike most common image formats. environment texture to a scene for illumination. Texture Environment lighting can be set through the OctaneRender Effect > Render Settings > Environment:

The Texture Environment may also be set through the Octane Interface:

After adding the Texture Environment node into the node tree, it is essential to tell After Effects that an Octane Node is being used for the environment. This is done by adding an Environment Out node and ensuring that the Texture Environment node is connected to this and the Render Target node:

The Texture parameter can accept a color (RGB), a value (Grayscale), or a texture map.

Other parameters associated with the Texture Environment:

• Power - Used to adjust the strength of the light. This can affect overall contrast and exposure level of the image.
• Importance Sampling - This toggles the importance sampling of the sky texture similar to the importance sampling in the texture environment.
• Medium -The medium in the environment (free space). This attribute is ignored when this environment is used as the visible environment.
• Medium Radius - Controls the radius of the “virtual” sphere created around the camera when an environment medium is used.
