Generate a HDR envionment map as a texture.
Daylight HDR
Method #
This node generate a simple sky envoronment, including a sun, sky, and atmosphere. The generated image has a High Dynamic Range, capturing a wide range of luminance, allowing for accurate reproduction of both bright and shaded details.
It’s possible to adjust the position of the HDR environment in 3D space to control the orientation and direction of reflections and shadows in the scene.
This node can be connected to any node which accepts an image input, although primarily used in conjunction with the Environment Image and Skylight nodes.
Parameters
These properties control the core behaviours of the node.
Parameter Details Active These properties control the core behaviours of the node.
Preview In Viewport Preview the generated image as an overlay in the viewport.
- Off : No preview is generated.
- RGBA : Preview the image blended with alpha in the viewport.
- RGB : Preview the colour channels in the viewport.
- Alpha : Preview the alpha channel in the viewport.
- PIP : Preview the image blended with alpha in the viewport, in a smaller picture in picture display, on top of the existing content.
Width The resolution of the generated image horizontally.
Height The resolution of the generated image vertically.
Brightness Overall brightness of the generated HDR.
Eye Height Height off the ground the sky is being generated from. Higher values can have less atmosphere and lower the horizon level.
Atmosphere Height How far the atmosphere reaches from the ground. Higher values can make the atmostphere appear thicker, while lower values can make the atmosphere feel thinner.
Atmosphere Density Controls the density of the atmosphere. Higher values can make the atmosphere thicker and warmer, lower values can make the atmosphere feel thinner and colder.
Atmosphere Scatter Controls how much the atmosphere scatters on the horizon.
Night Colour Controls the ambient colour of the sky, without light.
Sun Disc Brightness Brightness of the sun disk.
Sun Atmosphere Spread How much the brightness of the sun spreads in the atmosphere.
Sun Disc Size Size of the sun in the sky. Changing this value will affect the resulting brighness in the scene, as a larger area emits more light.
Sun Disc Falloff Control the falloff around the sun disc.
Sun Disc Falloff Exponent TBC
Sun Azimuth The suns position horizontally in the sky.
Sun Elevation The suns position vertically in the sky.
Geolocation set a specific position in the sky the sun appears in based on a location on the planet.
- Auto : Uses your current location to set the sun position.
- Manual : Set a long/lat position manually to place the sun in the sky.
- Off : Uses Sun Azimuth/Elevation instead.
