Light Omni
Light Omni is a point source emitting light in all directions (360 degrees) and realistically reproducing shadow cast. This type of light serves to simulate light sources with bright center and equal roll-off of intensity. An example of such a light is an ordinary household lightbulb, uncovered and hanging from the ceiling. Light Omni proves useful for general lighting purposes in indoor scenes because of its nondirectional qualities.
Please note that as Light Omni uses cubemap modulation, the shadowing by this source requires 6 passes and can be expensive.
Light Omni has a variety of shapes and, therefore, can be used to create area lights, for example, realistic interior or street lights.
