Slim Light Templates available for download:
Searching for more control over lighting I developed some slim templates. They're mostly based on the All purpose shaders that ship with RMS so they're not a big shift if that's what you normally use. They do add some nice lighting features.

Modeled by Jeremy Vickery.

Features described a bit more elaborately here (http://minaragaie.posterous.com/modern-lights-for-renderman-coming-soon#!/).
Download available on Pixar's Renderman depot website here (http://renderman.pixar.com/confluence/display/rman/Mina+Ragaie+Slim+Light+Templates).
Soft Shadow maps (using single single map) originally developed by Bertand Bry-Marfaing (http://www.3db-site.com/html/softShadow.php).

1- Sharing shadows between lights:

Directional occlusion

3-More control over light color:
Add saturation as the light looses energy and shift it's hue along the spectrum

Complex light gradient created by picking the light color at full energy and at zero energy.

I'd love to see these features come across to other renderers as well. Hope it sparks some inspiration.

Cheers,
Mina
