This time I talk about the awesome Probelight, and how to use the damn thing in your own levels.

Probe lights ~
Omnidirectional high dynamic range image that records incandescent illumination conditions at a particular point in space. What it means is that it takes a 360* picture, hence the omnidirectional part, then blurs it, and uses it to create lighting for a model, so it looks at the model's polygon's normals, which could be though as a perpendicular line from the polygon, and says "Well this polygon looks at this area of the image I just took, let's apply the color of the image at that point, to this polygon's lighting value"

When starting a new level, it is best to have one probe light with a really large range (But it depends, if you're level is a set of canyon small corridors, multiple smaller ones will be more beneficial) and make sure to place it in a location where the view is an average of what you would normally see, like high above the map where the ratio between sky and ground is almost 1:1. Remember that the larger the angular diameter (apparent size of object seen in cube map) the more of an influence it'll have to the light generated by the probe light ( as seen in 7:03 )

Ambient lighting blends between probe lights, depending on the overlap of their ranges, and the closeness of the probes in which a model's in, so even though you have a global large probe, smaller ones will almost 100 percent override it without any blending between the probes.

You bake a probe with Shift + B

Size of generated cube map can be set by adjusting the Reflection Texture Size
Default is 16, and if you set the value to -1 after you've changed it to something other than the default value, that value will be kept for future bakes.

You can control the diffuse contrast and ambient strength of a probe light by expanding Probe Light, and adjusting Ambient Modulator and Diffuse Contrast (Later not available in Earlier engine versions such as Sam HD series)
