I saw on the F-prime product page, there is a movie sample that they use LightWave Luxigon tool, it makes the render image look extremely good, can somebody tell me what is this, how to find it (or purchase)?

Thanks

Luxigon is a not an external plugin, it's included with LW. it allows you to get a lighting set based on an object geometry (one light per polygon). You can try this out with a sphere made of say 36 (6x6) polygons facing inward (use flip to do this). The luxigon tool will convert this simple object into a set of 36 lights pointing to the center, which comes in handy to fake aglobal illumination effect (just like using a backdrop color with radiosity turned on). For further explanation, check your manual

luxigons are basically normal polygons in modeler that are assigned a special "luxigon" attribute. When you bring them into Layout, they don't do anything special until you "convert luxigons" then every point of the polygons that were assigned as luxigons are converted into lights with attributes that you specify (intensity, light type, color, etc). It's EXTREMELY useful for placing large numbers of lights in specific arrays, and can create soft shadown effects like the worely demo because you use so many lights that the shadows cast by them overlap and become "soft".

Not sure any of that makes sense, but it's a great tool and you should definitely learn it.
