[Pbrt-discuss] help! plugin problem.

[Daniel Neilson]

  This may seem like an odd question but, did you try inserting the same 
printf()'s into grid.cpp to see whether they return the same results if 
you use a grid rather than your own plugin? It's been forever since I 
tried to do any pbrt coding so, I don't remember whether what you're 
seeing is "normal".
