It can be connected to the inputs of nearly all other bricks. Only one User Parameters brick can exist in a shader network at a time. It can be found within the Bricks > Functions > Utility category of the Brickyard. The User Parameters brick is a new brick designed to control what the user sees in the related property views of the interface. So rather than adding various lights to a scene to imitate a scene's projected lighting, environment mapping includes all the real-life lighting the scene needs.

HDR image environment maps use pre-calculated HDR images to calculate reality and interpret the image. HDR images work with the human eye to increase or decrease the way light appears in a scene, like the pupil naturally does, and use tone mapping to set the light range within that scene. In comparison, to compensate for sunlight, the pupil contracts when outdoors to let in less light.

For instance, when indoors the eye's pupil will dilate to let in more light, allowing the eye to see more light in the room. The eye naturally adjusts to how much light it takes in when indoors or outdoors. In other words, HDR images display digital light in the same manner that light appears in everyday life by considering how light and the human eye work together. Linear high dynamic range (HDR) images participate in lighting the scene and are simple lighting setups that are based on real-world environment captures.
