Method
Add an environment map node to a scene, add an image to the nodegraph and plug it into the environment map node. You should Ideally use .exr of .hdr images – HDRI Haven is a great resource for these images.
The environment map output can be plugged into both skylights and skyboxes for an even better visual response.
*Make sure to enable environment maps in the material of any objects that you want to see it on.
*Projects will load much faster when you use .exr as opposed to .hdr files for environment maps.

Envmap Image |
Image used for the environment map. |
Brightness |
How bright the output environment map is. |
Specular Amount |
How much the environment map is added to the specular of objects |
Diffuse Amount |
How much the environment map is added to the diffuse of objects |
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.
|
Apply Mode |
How the Environment Map is applied to the mesh.
- Reflection, The image is applied as a reflection on the surface of the object.
- Refraction, The image is applied as a refraction of light through the volume of the object.
- Direct Mapping, The image is applied as a spherical map onto the surface of the object.
|
Sample Quality |
The quality of the sampling done across the mesh for the mapping. |
Resolution |
Resolution of the generated environment map. Higher resolutions can impact performance a lot. |
Refractive Surface Thickness |
When in Refractive mode, control how refractive the object’s surface is. |
Max Input Brightness |
Maximum brightness from an image that will be applied. Usually useful with HDR images. |

Outputs
All nodes connected to this node are treated as if flowing to the parent node, and inherits any transformation changes along the chain.
