instances' filename length limit (was: Re: [Radiance-general] replmarks in 3.6)

[Greg Ward]

Hi Lars,

What you are running up against is the general limit to the length of  
individual words in Radiance scene files.  This is set by the MAXSTR  
macro in src/common/object.h.  You could change this macro value and  
recompile, but it should not be necessary.  The instance type can give  
a filename minus the directory path and it will perform a search of all  
the directories in the RAYPATH environment variable.  You can simply  
add the path(s) you want included to this variable and execute  
replmarks in the directory containing your instance octrees so that it  
produces only the final path component.

Is this the problem you were having with replmarks in 3.6, or is  
something else wrong as well?
