I am using Pixie to try and render an example for a research paper, but do not want to have to do photon mapping since my algorithm would require me to rewrite the photon mapping functions. If I am not mistaken, it should be possible to do a 1-bounce indirect lighting render between diffuse objects using irradiance caching without photon mapping. It should work similarly to this example: http://www.renderpixie.com/pixiewiki/Examples/RIB_Examples, if you don't do the photon maps. My problem is that everything comes out black (the usual), and I ended up just doing a full gather at each shading point. This is mega slow! Has anyone ever been able to get irradiance caching to work without photon maps in Pixie?
