I forgot to mention that +c only works with the default render pattern.
Sorry,

Fantastic! Michael, and you others, thank you! This is all much clearer to me
now. I'm not just new to POV-Ray, but to 3D rendering overall. Trying out
different software and renderers at the moment, and I must say POV-Ray gives
really nice, characteristic, results.
Regards,
Lennie

When you are ready to post them, I am sure we all would like to see some
of your images - since you seem to have long render times, they must be
fairly complex.

Apparently, you are using the Windows version.
Don't use +c when first starting the render, only on an interupted render.
Put +c in the command line box, then click the Run button.. It's the
only thing you need to do.
Make sure that you resume using the SAME resolution that you used initialy.
If your scene use radiosity, the radiosity pretrace will be performed
again, but only for the un-rendered part of your image.
If using photons AND you did NOT save the photons to a file anr reload
that file, the photons shooting phase will need to be done again in it's
totality.
You don't need to use any rerun.ini file.
I highly recomment that you remove
Continue_Trace=on
Create_Ini=rerun.ini
from your quickres.ini file. That file is to be used EXCLUSIVELY to
store predefined image dimentions/resolution. Nothing else.
If you start from the console using pvengine64.exe RERUN, i don't think
that you need the +c. In fact, it may be the cause of your problems...
So, just une +c in the command line box.

Since you are new to POV I assume you are new to the newsgroups as well. You
cannot post images here. You must use the group "povray-binary-images". Be sure,
we will notice your uploads there.
Best regards,
Michael

Thank you John.
But really, they are nothing special at all. At the moment I'm just fooling
around with different scenes and settings. The reason they take so long to
render is because of the radiosity function.
Example 1
https://dl.dropboxusercontent.com/u/10144729/POVRAY/01.png
Rendered with radiosity, render time 14+ hours
Example 2
https://dl.dropboxusercontent.com/u/10144729/POVRAY/02.png
Rendered without radiosity, render time about 1.5 minutes.
It's a big difference between those images, but not 14 hour difference.

Forgot to mentioned these were originally rendered in 3840x2160.

...which is why they take so long ;-) That's approximately 8.25
Megapixels. As a rule of thumb, I try not to render anything larger than
1 Mp when I'm developing a scene. It's only when I'm happy with it that
I go large.
BTW Your example was really good. Are you sure you're just a beginner?

I was just surprised by the difference in time between the one rendered with
radiosity and the one without :)
And yes, still claim to be just a beginner. Installed Blender during Christmas
holidays, and in the beginning of January I decided to install POV-Ray as well.
This scene hasn't been coded in POV-Ray, that I would never (probably) be able
to do as programming (not even the easy languages) is far from my best quality
:)
But I will have a look into the coding later on, as it seems you can create some
really crazy stuff (abstract 3D) using it.
