Making luminares


Observation shows that many fixtures have at least two levels of light coming from them. Primarily, there is the light allowed out by the shade, and then there is a second broader area formed by the light that has reflected of the interior of the shade. Therefore, at least two sources must be used to reproduce this.

Essentially, one needs to create two points almost at the same place with their y axes oriented in the same direction. Depending on the shape of the fixture into which they will be set, these will be either round or rectangular shapes.

Then one simply needs to size the axes to control the shape and fall off of the lights. The softedge texture should be added to each. As with the world light discussed above, any number of variations may be made on this and saved as states. A group with one yellowish 45 degree spread light surrounded by an 85 degree spread with very broad penumbrae could be called a "flood" light. A different state with 15 and 20 degree spreads of near white light with only a tiny fuzz at the edge would make a passable "spot" light.
