[Radiance-general] ranimate, recovering from broken rpicts?

[Jack de Valpine]

Hi Lars,

I am not sure that I can answer everything here. But I will offer what I 
can. I believe that the recovery mode does operate as one (1) process 
not multiple. It would be too difficult to keep track of what is being 
recovered if there were multiple processes, rather with one process it 
just steps through to pick up anything that is unfinished. I believe 
that it is checking for .unf frames not .pic filtered frames.

Hope this helps a bit.
