    Hi

    I have seen that there is an old example 1 that used the irradiancecache function. But when I tried it, the renderer informs it does not know this function. Was the function already implemented in the early versions?

      The Irradiancecache() function is designed to store values in the irradiancecache.  We don't currently support it, but then Pixie has the ability to generate the irradiancecache from a photonmap on the fly, and to save that result so it can be read back in a more smooth form for a final render.

      I'll look at adding it, as it does allow some interesting / more complex effects to be created - though for normal global illumination usage, it's not needed.

      I'm going to write up a global illumination howto that will go through the various techniques you can use.

      Cheers
