Environment Image
Generate an environment image for a Skylight.
Environment Image
Method #
This node generates an environment image from a HDR/EXR image for a Skylight, or other lighting nodes.
The output from this node is an image texture which has been specifically prepared for lighting other nodes, but you can add some extra tweaks to it with Post FX nodes.
The output from this node is an image texture which has been specifically prepared for use with lighting nodes, but Post FX nodes aren’t supported directly. You’ll need to connect them to a video node, which can then be connected to the “Envmap Image” input.
Parameters
{message-information-attributes
Parameter Details
Envmap Image Image used to generate the environment from.
Image Source Mapping Select which mapping type was used in the image.
- Dual Paraboloid : Use 2 paraboloids to generate a cube map.
- Spherical : Uses Spherical Mapping which corrects for pole artefacts.
- Equirectangular (VR 360) : Uses equirectangular mapping, common for HDRi textures.
Resolution Resolution of the generated environment image. Higher resolutions can impact performance a lot.
Max Input Brightness Maximum brightness from an image that can be used. Usually useful with HDR images.
