I added the ability to take a screenshot that’s larger than the screen resolution.

Nice, here’s a little idea: Why not send the image to photoshop?
A few interesting links i found:
http://www.just-joshing.com/2009/06/03/open-bitmaps-in-photoshop/
http://area.autodesk.com/forum/autodesk-3ds-max/maxscript/max-last-render-to-photoshop/
just a short question ( as i did’nt test and install the script … )
i guess i does not work in Nitrous / Max2012 ? I see in the source that you are using gw.setPos, but that ( plus other gw related maxscript commands) is broken / do not work in nitrous …
UPDATE:
okay i tested it in Max 2012, and as expected it does’nt work, not even in Direct3D mode
in D3D mode it grabs an empty viewport, you might be able to repair this by doing the actual grabbing in a viewport redraw callback (see further docs [here (Max online Help)](here http://docs.autodesk.com/3DSMAX/14/ENU/MAXScript%20Help%202012/files/GUID-1B088FF0-6A36-420E-9F37-F0DBE9FB267-2008.htm ) )
In Nitrous display mode the grabbing works, but the grabbed size always sticks to the size of the currently active viewport. ( As i mentioned above SetPos does’nt work in nitrous)
Additionally all shadows and AO are there in the alpha channel ( because of the method how you generate it ) . I guess you would have to switch off all advanced lighting and rendering options in the viewport for you alpha pass first…
Otherwise a reall usefull script
@tassel, one guy from policuont forum will add new things to the script – go to post #10.
May be hi will add “send the image to photoshop”.
I can,t use max2012(my pc is too old). If you don’t mind – can you send me the maxscript help file from max2012, so I can see what is the new in maxscript for this 3ds max release.
ahh i see -the link is broken in that previous post of mine …
you can grab all from here (first entries)
http://usa.autodesk.com/adsk/servlet/item?siteID=123112&id=16707768
either browse online or download the maxscript help zip, you can extract it locally and browse it there ( just html files … )
Here’s the entry i wanted to link inmy previous post , but failed …
