Hi, Darren,
Problem is in the implementation. The method you propose is obvious and logical.
The problem is that I implemented rendering in TEMP dir of Linux and those do
not survive reboots. But this is only a minor issue, "the weight is in the
mind", said Zen.
NOTE: -C option actually clears recovery data, +C restarts after abrupt stop.
See: http://www.povray.org/documentation/view/3.6.1/217/
However, I need to test thoroughly before continuing, as this is a new feature.
I will test it on abrupt shutdown and blackout.
