You don't have to write shaders. It is sufficient, if there is someone, 
who can write. Or one can use some visual tools to compose shaders and 
let machine to do everything other. I browsed caligari newsgroups and 
found pretty impressive shaders for TrueSpace, created with visual 
composing program ShaderMagic (http://software.gallo.sk/shadermagic/). 
With such tool one can play like with lego. And there are similar tools 
for RenderMan shaders (e.g. Puzikov's ShaderMan 
http://www.dream.com.ua/thetool.html).
Oh, those impressive shaders for TrueSpace fake subsurface scattering 
and global illuminance, great interest topics here some time ago. Some 
examples:
