Help, please

After almost 24 hours of path tracing image of 1748X1024 resolution (it did some 320 passes) AutoCAD collapsed :( and all three windows had closed.

I didn't check the auto save option in Render Setting panel (what a stupidity).

Is there any chance nXt saved intermediate state of the picture somewhere?

Thanks.

I really feel sorry for you George. I know that have no utility, it' too late. I always set an autosave every one pass(!) (I know it's too much), and in "tif" with alpha layer. Especially when I start a long render time. The only last chance is, one more time, Roy... But I'm pessimist.

[Roy Hirshkowitz]

No-- nXt doesn't Autosave by default.  I'd be willing to make autosaving every 50 or so passes the default setting.  You can do the same by using your template drawing.

[Chas / Aug Posekany]

I guess to meet most of our needs it would have to save after the set number of passes and keep rendering without user input.

[Roy Hirshkowitz]

It does.

[Chas / Aug Posekany]

That's what I get for paying attention.

I never noticed that there was an autosave option in there.

I thought you could just set the total number of passes.

Once autosave will be on by default, file naming issue comes to place - what will be default name and path? As mentioned in point 12 here, we have already overwritten couple of final renderings because of autosave...

[Roy Hirshkowitz]

It will overwrite the file.  I may get around to improving this at some point, but for right now this is intended as an emergency save mechanism only.  Do not rely on this for final render saves or you will get in trouble.

Long time ago in AR3 (I don't know if it was available in AR4) there was an option of saving radiosity file of solved radiosity solution of model. It could then be used (if model stayed unchanged) to continue in producing more renderings.

Would it be possible to have something similar here? I mean some sort of "finalized" 3D model translation file, which would contain all settings, lights, materials, views and so on, completely separated from original dwg file, containing all data used by nxt AFTER it loads model to walkabout window and furthermore, if rendering process starts to have capability after stopping it to save some sort of "NXT internally crunched" data file in a way to be able to load it into nxt somewhere else or later and to continue render from the point it was stopped previously?

I have also asked for that too in the past, so seconded.

[Roy Hirshkowitz]

Unlikely within AutoCAD.  I've got a stand-alone path tracer that works that way.  I need to get back to it at some point.  It reads AutoCAD/nXt models.

[George Ioannidis]

Will it be available some day? Will it be capable of doing renderings using other modelers somehow? What is the general ground of having this as a stand-alone program Roy? Can you reveal some more secrets to us? :)

[Roy Hirshkowitz]

I'm honestly not sure where it's going.  I'll put out a version for people to play with at some point.
