Octane Texture Environment Light

Texture - Accepts an HDRI image. If this attribute is left at its default value, it acts as an intensity slider for a consistent environment color. A value of 0 creates a black background and blocks out any ambient light.

Power - Controls the power of the HDRI image lighting. Increasing this value makes the scene brighter. This functions as the Brightness attribute regardless if a Texture is connected to the Sun Sky node.

X/Y Rotation - Rotates the HDRI Image (in degrees for X and Y).

Pitch/Bank - Adjust the pitch and bank of the HDRI Image

Medium - Accepts a Volume medium to add volumetric illumination to a scene.

Medium Radius - Determines the radius of the Volume medium that's connected to the Medium attribute.

OCTANE Texture Environment - The output of the node is plugged into the Environment pin on the Render Target node.

Texture Color - Sets the texture background color (if an image is not used)

Power - Controls the power of the HDRI image lighting. Increasing this value makes the scene brighter. This functions as the Brightness attribute regardless if a Texture is connected to the Sun Sky node.

Heading Rotation - Rotate the image either left/right (in degrees).

Y Position Displacement-

Pitch Rotation - Adjusts the image pitch (in 3d space) of the texture Image node.

Bank Rotation - Adjusts the image bank (in 3d space) of the texture Image node.

Importance Sampling (toggle) - Enables quicker convergence (noise reduction) for HRDI images by applying importance to certain areas of the HDRI in order to sample rays that resolve to important areas more often than unimportant areas. This means the ray tracing is more efficient as it is not wasting time on rays that do not contribute much to the overall image quality. Due to the added complexity, this reduces the Ms/sec speed of rendering, but each Ms is more efficient, resulting in higher image quality in less time.

Medium Radius (m) - Determines the radius of the Volume medium that's connected to the Medium attribute.

Backplate Visible (toggle) - Toggles backplate visibility on/off.

Reflections Visible (toggle) - Toggles reflections on/off.

Refractions Visible (toggle) - Toggles refractions on/off.
