I am using Yvo's 3.7.0 RC6 unofficial (Universal 64 bit, Dec 14 2012) in OS X to
research turbulence models in the atmosphere, using clipka's focal_blur camera
that allows you to specify the number of test rays.

However, I've bumped into the max_trace_level limit of 256.

Any chance of making a special edition for OS X/Yosemite that boosts this limit?

Although I haven't published my research results yet, I do have a whimsical
POV-Ray picture of what I'm up to at

That would certainly be a job for Yvo himself.

Building such a version should be a piece of cake (for someone familiar 
with building for OS X); from what I see, it should suffice to build 
with the preprocessor macro MAX_TRACE_LEVEL_LIMIT predefined to 
something larger than 256.

There might however be other limitations lurking in the shadows; they 
probably won't kick in right at max_trace_level 257, but don't expect 
max_trace_level 1000000000 to work flawlessly ;-)

That is a very old version, please download the most recent version at:

To what value? Here is a version with a limit of 1024:

Thanks! I will try it out this afternoon.  The reason I used the old version is
a combination of laziness and fear of upgrades.

1024 will help a lot.

Works great, thanks. If I need more, I hope you'll be willing to make another
version. It's possible to run really huge refractive simulations on Lonestar,
which has POV-Ray:
