This node generates a multi-plane image. The image has named planes
C plane contains the "right"
You can use this image in shaders with
Environment map or
parameters. You can render the image to disk using a
Composite output node, or refer to this node’s output
op:. For example, if you have a Sky environment map node
/img/skyenvmap1, you can refer to its output in a shader parameter using
Sky environment map is a digital asset. You can double-click it to go inside and find two lower-level asserts, skycube (for ramp-based images) and skycubedaylight (for simulated images). These assets may be interesting to technical users as examples of VEX-based compositing nodes.
Controls which of the following parameters are available to set the position of the sun in the image.
The Euler rotation angles to align -Z axis vector towards the sun.
The explicit vector that points towards the sun.
Azimuth of the sun in the image. Note that the default plane (
C) shows the
right view, so
90 will put the sun straight ahead in that view.
Elevation of the sun in the image.
Latitude of the observer, used to compute the position of the sun based on the date when Use is not Angle and elevation.
Longitude of the observer, used to compute the position of the sun based on the date when Use is not Angle and elevation.
Date of observation, used to compute the position of the sun when Use is Location, date, and time.
Time of observation, used to compute the position of the sun when Use is Location, date, and time.
Day of Year
A (fractional) day of the year (for example, 0.5 would be noon on January 1), used to compute the position of the sun when Use is Location, date, and time.
Controls whether the sun is rendered using a physically realistic simulation or using an artistically controllable color ramp.
The Realistic option is especially useful when animating the time of day, since it automatically produces realistic colors for sunrise, sunset, high noon, and so on. The Ramp option gives you artistic control of the colors, but does not simulate atmospheric effects, for example along the horizon.
Controls how sunlight scatters in the air, used when Use is Realistic.
Controls the brightness of the sky, used when Use is Realistic.
Manually sets a color ramp from the sun to the surrounding sky, used when Use is Ramp.
Render Ground As;
Sets the albedo of the ground.
Sets the orientation of the ground plane. Only used when Use is Ramp.
Sets the horizontal elevation of the viewer. Only used when Use is Ramp.
