Not quite sure what you are seeking help with. can you describe it more in depth?

does anyone else see non-compiled for each to be much slower than Copy Stamp?
since it's not always possible to compile I think it's quite a big deal

Is it just this example that is slow, or are real setups that aren't simply making a box each iteration slower also?

I spent the weekend moving a copy stamp from a city builder into a compiled forloop with multithreading on an 88core machine. Cook time went from ~15 min to 30 seconds for ~13,000 buildings with a combined total of 31 mil points.

I have been trying to find an illuminance loop method for the newest version of prman, but nothing I've found in the risnet has the illuminance globals. I need L and E. I have tried a variety of methods, but all have been fruitless. Is there a node for writing my own shading script where I can call an illuminance loop? I built a working network in mantra material builder but now I need it in prman. Anyone know how I can get these variables?
