Simulates lighting in the scene based on an image of an environment. Image-based lighting can use High Dynamic Range Images (HDRI) to simulate realistic lighting and reflection effects.
You can specify only one image-based light in the scene at a time. Other light types can be used with image-based lights and the overall scene illuminance is cumulative.
Specifies the strength or brightness of the light source.
Locks the position of the light source to the camera. When the camera is rotated or tumbled, the effect of the light (specular highlight) changes relative to the model’s surface.
Displays the light’s transformation grip. The grip display depends on the light type. For a point light, a move grip appears to let you reposition the location in X, Y, Z. For a directional light source a rotate grip appears to let you rotate the direction of the light source.
Specifies the image file used as the light map. An environment is simulated around the model which affects the model’s overall luminance and also appears in the material’s reflection component.
