  Multiple render jobs in a single instance (Message 1 to 10 of 10)

I think it could be a good idea to support multiple render jobs running 
in parallel in a single instance of POV-Ray. You could manage them like 
downloads in a download manager or bittorrent.

Why, do you ask? Because when running multiple instances it can get 
confusing as to which instance is currently running. Over the last week 
I've accidentally stopped a long render a few times because I clicked on 
the wrong icon in the taskbar.

Also, it resolves the issue where some files are open in one instance 
but not another, and POV-Ray does not correctly remember which files 
were open when starting a new instance.

Lastly, the "recent files" list at the bottom of the File menu may get 
messed up with all the separate instances.

I don't think this is a high priority, but I thought I'd throw the idea 
out there.

Don't you get a warning if you try to stop a long render?

You know, of course, that the windows version has a render-queue, in
which you can put the different jobs.

I did know that, actually.

Unfortunately, I still get confused sometimes and click through the warning.

Ok, Mike thinks of a Render-Que ahere multiple "Scripts" render at the same
time,
and where you can give each of the renderings more or less priority.
In my experience this will only make sense, if it will survive a computer-reboot
without big problems.

That is true. You should be able to continue where you left off after a 
reboot.

(Currently you can use POV-Ray's +C switch. But does this work with 
multiple scenes?)

Internally POV-Ray 3.7 can render multiple scenes at the same time. There is
just no user interface to make use of this feature.

Possibly there is some "Overhead" in doing trhese switches often, unless it
would definitely dedicate CPU-Cores to each Task?

The overhead of rendering multiple scenes in a single instance is less than
running multiple instances and rendering in each.
