New Build (276)

[Roy Hirshkowitz]

Added Combine Path Tracings... option to the Image Editor and made the farm use this method when you send it single frame Path Tracings.  See what's new for more.  A farm build to clean up a couple bugs is coming soon (today?).

This feature seems to be working pretty well, but it will need some testing.  It's pretty powerful for those of you using the Path Tracer.  With this option, you can:

• Add additional passes to any Path Tracing later on by combining the resulting .nXtImages.
• Continue processing in the event of a power outage or other interruption (provided you have autosaved an .nXtImage.)  Just start the rendering again and combine the autosave result and the new result.
• Send a single frame job back to the farm for more work and combine the old and new results.

Path Tracer only.

Great great news!

hurray! Keep on rockin' Roy

solo se podra combinar en la opccion FARM?

[Roy Hirshkowitz]

No, the Farm is not required to use this feature.  

If you do use the Farm for Path Tracing single images, you will need to use this feature to combine them.

Should have two renderings going simultaneously on the same pc of the same drawing (with one as read only)  in two different AutoCad session with each auto-saving as a different name.    At the end of 100 passes on each and I combine with IE I get 200 passes worth of rendering right?

[Roy Hirshkowitz]

You would yes-- but there's no advantage to what you're suggesting.  If you run two sessions on the same computer, each one will run at half speed.

[akinlolu olugboji]

I know what I would be doing is being able to continue rendering at a later time, while waiting for Nxt Cloud Rendering to kick off.

[Roy Hirshkowitz]

No-- what you are doing with the procedure you outlined above is wasting time.  Don't do it.

[George Ioannidis]

Let me see if I got it right. I am running path tracer for quite long time, say five hours. Suddenly Acad freezes. nXt was set to make auto save of render image every 10 passes (using *.nXtImage format - little bit slower than saving to anything else, but essential for further "post process") so there is an image file saved on disk. After Acad crash I do reopen the drawing file. How can I continue on rendering from where it was before the crash? When I hit render button again, it will start the whole process from the beginning, so how can I skip all of the passes already made in previous rendering before the crash? In image editor I can combine the two successive nXtImages in Image editor, but will it refine anything if I use the first, 5 hours image and the second, say another 4 hours? Please Roy, give us kindly some more informations on all that. Thank you in advance.

[Roy Hirshkowitz]

Just start a rendering again.  Whenever you stop it, it can be combined with the old one.  It works (if I've done everything right) because every rendering you do with the path tracer is unique and non-deterministic.  In your example you will get the rough equivalent of a nine hour rendering.  BTW, AutoCAD should not be suddenly crashing-- I'm interested if it is.

[George Ioannidis]

Oh, I was just assuming possible situation why rendering could stop for some reason, so do not worry about sudden crash. Other scenario could be the following: I am rendering an image in my office. I do not want to leave my machine turned on for the night, so I stop rendering, save nXtImage and drawing, back it all up to external drive and continue on rendering at home on my home machine for the rest of the night? Really GREAT new, Roy!

[Roy Hirshkowitz]

Yep-- you're getting the idea.
