Hi Lars,
You are correct about this. There is a limit to the number of
materials that may be included in the ambient exclude list (2047 in
this case) or the trace set of rtrace (8192). I could raise these
limits in the distribution, or you could yourself by adding:
-DMAXASET=N -DMAXTSET=M
to the build options in the makeall "rmake" script and recompiling.
All I was saying is that there is no fundamental limit to the number
of times a material may be redefined. You can say there is a limit
with respect to the include/exclude settings, but this is not the
same as a basic limit. If Jelle wants to exclude his reused material
name, then he may have a problem.
