Translucent Objects with RenderMan
Light-R 0.30 is a free LightWave 7 & 8 to RenderMan exporter. It's not yet finished but at this point is more than just a prototype. Now the program supports PRMan, Aqsis, 3Delight, Air and Pixie. Thanks to all the testers for sending bug reports and ideas.
Doom of Lights 1.1 is a LightWave script created to simulate radiosity and soft shadows quickly. UPDATE: Bug fixed - now is not mandatory to have Auto Key turned on.
3 to 4 points This LightWave script creates a point based in the position of other 3 points (vector geometry), the 4 points are co-planar (all are in the same plane).
Speedy Polygon This LightWave script is the same as the above 3to4points.ls but after creating the new point it creates a 4 point polygon, very handy!
Box'O'Nulls Tired of using the same old nulls? Not anymore, now pick a figure from a list, as seen on TV.
