Haha - nice suggestion

guess i should push hard to refine stability and features than...
don't want to cause Autodesk's problem report database being flooded even more than it already is ...

I don't see why not, it's silly for them to push Nitrous and then completely lack an ability to capture it to stills or video. The functionality is sorely missing, and I don't really like the "oh, just use Quicksilver" logic, since there are sometimes differences between Nitrous and Quicksilver.

I am getting a bug though when using PP, in that it seems to capture the first frame of my video well, but subsequent frames are low quality, even though they still take the same amount of time. I am saving each frame to a .png file, could this be the cause of my issue?

PNG works fine, i use them myself, because of that still existing 1GB AVI file bug

Depending on the scene you render, try to disable the "use iteration limit" button
Nitrous might itself fail from time to time ( does that in the standard viewport too)
Best method is to use a high timelimit on the first frame-> when it looks okay -> fine, reduce the time limit. When somethings wrong -> toggle some nitrous option to "reset" the refinement process ( nitrous starts from scratch for that frame..)
By bad quality you mean no refinement going on, everything looks like it was without progressive refinement ? Meaning you don't notice any smoothing in the frame over time ?

Realy thank for this script, is realy perfect, but i have problem to do 2k (2048x1556) previews, the first frame looks good bud every next is it has 2k resolusion but image is stretched it looks it is zoomed from maybe 640x480 resolution.
I figureout that it happens to me only with complex scenes for example whent i tryed to preview cloth simulation with many verticles and tearing , (normaly also clicking on timeline takes maybe 30 secons to standart viewport refresh). If you want i can send you scene

Thanks again for this tool, and right now I'm using it intensively for creating all the preview stuff for my current project.

Some minor quibble from me:

- I sincerely hope you can find away to allow switching to another window while rendering the preview, while Nitrous refinement still keeps going! Viewport previews are alreaady saving a lot of time as they are, but it would be even better if I could work in another window/program while rendering.

- Frame numbering is driving me nuts: each file sequence starts at 0, instead of just taking the actual frame numbers for it... I guess that's quite an easy fix ;-)

- Tiny one: Viewport snapshot isn't snapshooting (is that a word?) the current frame, but the start frame set in the preview time range... grabbing the current frame would be more sensible, I guess.

- It would be a good idea to have PowerPreview disable Max's autosave while previewing, as it messes up the preview when it happens during rendering (the preview window gets switched to full screen, thus getting a different frame size for the rest of the preview)

- An option for disabling the ViewCube in perspective views

- And some feature requests at the end: Output of Alpha-channel (or at least a "silhouette" render style), Z-channel, Object Masks, Ambient Occlusion, Shadows and whatever Nitrous supports.

Thanks for such a great focused feedback....

Please always check the latest update on the scriptsot page, some of your issues are fixed in the latest version ( as far i remember )

that's a hard one, i don't excpect this to be possible if Max keeps acting that way in future versions... but never say never

AFAIK i've fixed already, check the latest version

That's definitly fixed in the latest version

good suggestions, totally forgot about the viewcube, because i have it disabled and never use it ..

that's on my planned featurelist, but currently the whole thing is on hold again, because i've got plenty of contract work to do ( which pays my bills ). But i'll be back on powerpreview as soon i got the time again ..

best regards, Josef

Ah, right, I was still using 0.50b and only checking this thread for a newer version. I'll install 0.50c immediately

BTW, I've noticed a bug (and this time it's in 0.50c as well) - take a look at the attached image: It looks like some pixel lines and columns are missing... or doubled... or just shifted... I can't really tell. Happens every now and then. Looks like there's some scaling going on, and with no interpolation happening, it has to resort to line doubling, or whatever that is.

Yeah - i noticed that strange thing too, looks like during the grab->copy->write to file process some unintentional scaling is going on, i suspect it during that process the height or width gets changed about 1 pixel -> which would lead to that issue ...
A fix for that is on my radar too, but as i said , i can't say when i got time again for the script ;-)

Just put another update online -> here is what it fixes
-------------------------------------------------------------------------------------
UPDATE: 2012/02/15
* Filenaming with image-sequences ( wrong frame numbers )
* Double gamma applied when doing snapshots with display gamma enabled is fixed
* Viewcube/Steeringwheel now are hidden during preview/snapshot
-------------------------------------------------------------------------------------

that small scaling problem is not fixed -> will hunt it down when time allows

posted another HOTFIX for problems that appear when people have completly "wiped" the viewcube plugin from their installations ...
Please read gamma related notes in the history section too, if you use display gamma....

Posted the next Version (V0.60 Beta 6) on scriptspot

http://www.scriptspot.com/3ds-max/s...itrous-previews

This one supports 3ds Max 2013 and adds some handy features for the new Nitrous goodies, like DOF/Bokeh handling and the improved standard "Make Preview" functionality.
Adds some other things of course too, like token based target-filenaming etc...

See the description about the update on scriptspot

I finally got some time to play with this script and i have to say it is very useful.
One thing i have issue with is getting the aspect ratio to match the viewport.
I did some simple test but no matter what i try it always comes out stretched
vertically at 800x600. I'm probably doing something wrong, can you point me in
the right direction please?
