The program is already running. OK, I want to run it anyway

I am currently running a raytracing walkthrough. ETA  1 day+.

 

And now I'm stuck waiting for it to complete. Why can I not run another instance?

You can so long as it works to share computing resources.  Hold down your CTRL key while you start the second instance.

 

It is just not a recommended thing to do.

ah great, that's the trick I was missing.

Yep the program works just fine running twice. I guess I'll have to be somewhat careful trying to edit the exact same file so better make a copy etc.

Yes you need to be very careful that if you have the same file open in two instances that one file is only used as a reference or you will end up with quite a mess.

I'm not sure I understand why you need to open the second instance at all.  There should be no reason you can't continue to work with the open instance where the Ray Trace is running.

Ray tracing of a walkthrough. X13 is fully 'frozen' with a "frame x out of xxx" window slowly progressing.

I see.  I glossed over the "walkthrough" part.
