The color of the sky at the horizon. Overall sky color is linearly interpolated between Sky_color and Zenith_color.
The color of the sky at the zenith (straight up). Overall sky color is linearly interpolated between Sky_color and Zenith_color.
The color of the simulated fluorescent lights. These “lights” produce reflections in surfaces, but they do not actually illuminate surfaces.
The Light Placement parameters control the size and placement of the simulated fluorescent lights in the environment. These “lights” produce reflections in surfaces, but they do not actually illuminate surfaces.
The Floor Parameters control the appearance of the environment’s floor.
The color of the floor, the floor’s horizon and the floor’s grid.
If Real_floor is OFF, the environment’s floor is located at infinity, so reflections on moving objects or reflections viewed from a moving camera will be incorrect. The default setting is OFF.
If Real_floor is ON, the floor is located on the ground plane, so reflections on moving objects or reflections viewed from a moving camera will be correct. If Real_floor is ON, make sure surfaces or the camera do not go below the ground plane.
