Title: EXR autosave problem with backburner
Post by: DotDesignStudio on 2017-03-14, 10:31:33
Hello,

Since Corona 1.5 the autosave exr is placed in system settings. Previously it was connected with the scene, now it is connected with 3ds max settings on specific machine. So when i render with backburner i can't save corona raw exr for further tweaks or resuming render. I can't open 3ds max on rendering nodes, it will start trial and make them usless as render nodes.

Please move the autosave exr from system settings back to general settings.

Mike.

You can Add Corona beauty render element and set it to save .cexr anywhere you need. this render element is saved on per-scene basis. Does that solve the problem?

Autosaved corona exr lets me to resume render. Does this beauty pass contains all of the channels?
If i set exr save parameters in beauty pass channel and then change save path it will mess with the beauty settings.

Autosave function saves incrementally. It is nice when something goes wrong. Having just one save at the end does not count as autosave.

oh, for incremental scene-specific updated you will have to do script-based solution I am afraid

Well, it was working already in previous versions. I propose to change it back in the next release. I see no reason use in this change. Maybe only one thing is that there is one line less in UI. It's not a good bargain.

All information to make resume possible, autosaved exr = cexr. If you only need this kind of file to resume/adjust on your main workstation, you could alternatively just use cexr in the standard output so you don´t have to mess around with render elements.


As for autosave and not being able to start Max on a render node and configure it because it´s not in demo mode anymore:

1. You can use string options (https://coronarenderer.freshdesk.com/support/solutions/articles/5000518663-string-options) to change autosave for specific scenes, e.g.:

Code: [Select]
bool vfb.autosave.enable = true
string vfb.autosave.filename = C:\\Temp\\DotDesignProjectX_autosave.exr
float vfb.autosave.interval      = 20


2. You could change the Corona system settings config file on a node with some (utf-8 capable) text editor to match your needs for all jobs (...\plugcfg\corona\SystemSettings-<somenumber>.conf)


Good Luck

Hello,

Thank you for your input.
Unfortunately cexr format is usless with backburner. I get error when server (afrter completeing the render) tries to save each channel in cexr format. It tries to save it with *.cex extension  and it all dies, render restarts.

So, this is another reason why i suggest to move back autosave box out of the system settings.
Placing it in the system settings annoys, because it is easy to forget that it was on in previous scene and just overwrite it with useless test. I have just overwritten last jobs autosave with two teapots, while making this test.
Having it with save vfb/ resume from file /resume render  just makes more sense.

Mike.

This is a known issue (https://forum.corona-renderer.com/index.php/topic,13322.0.html) afaik (never used it myself) - even not related to BB. I think Ondra has just forgotten about this. But what works is to set the standard output to cexr format (without render elements). All in all not very handy.

Personally I would go for string options to override autosave.


Good Luck

the bug is scheduled to be fixed for 1.6 - unfortunately 3dsmax clamps extensions to 3 characters ;) we did not count on that
