Is there a way in AutoPano Giga to render the final panorama into smaller tiles for easy editing?
So if the final panorama would have 20000*10000 resolution, for example, the result would be 100 smaller images sized 2000*1000, for example, that could be assembled like a mosaic into the final panorama.
I am asking since this would help editing/retouching the final result.
Thanks!

Welcome to the forum...
This utility may do what you want?:
http://www.bigmike.it/kroutils/
Online
next to kroutils 2 other ways are possible:
using panotour. loading the pano and than exporting to cube files. (with ptp 1.8 the reimport to create a rectangular again is not possible, shoudl come with ptp 2.0)
and the krpanotools contain tools named kmaketiles, ktransform and kcube2sphere tools where in/output filesize and format can be defined. (tool is windows command line based...)
Liebe Gruesse,

Thanks, I am checking out kroutils. I take it there is no built-in function to split the output into smaller images?
Cheers

Some feedback...
Kroutils seem to require RGBA file format. Unfortunately, I rendered my .kro without alpha, in an attempt to save space (what is the alpha good for anyway?).
When loading the file, kroutils complained about this, but let me continue - which resulted in 38476 files before I could kill it!
So I guess I need to rerender with alpha...

Why would you need an alpha?
20000x10000px is a rather small image. No problem at all to edit it in Photoshop.
If you want to edit cubefaces: use KRPano´s droplet "convert sphere to cube", edit the 6 faces and use "convert cube to sphere" to make it an equirectangular image again for the use in PanoTourPro.
But be careful: editing tile-/face-wise you can produce visible seams in the pano when you edit close to the borders of the faces.
One of the very important basics in dealing with somewhat larger panos: get Photoshop and at least 16GB RAM in your machine.

Correct - there is no built-in function in APP/APG.

That's what I am wondering, too. I personally do not need any alpha channel, but krtools complained they are missing in my first .kro file. So my conclusion was that I should include it next time?

That was just an example. In my case, I am planning for a much larger image, more like 120,000^2

Not sure cube faces are the right way here, as I am not dealing with a closed 360 degree panorama.
It's just a little curious that APG is designed for gigapixel output but has no mechanism to break that down into smaller chunks for potential post-processing.
Thanks for all the input!

Hey Martin!
Well - APG can´t know about your preferred workflow . . . 
Dealing with large panos/mosaics it´s quite obvious you need some very special requirements regarding your hard- and software besides of APG 
Breaking large images into small chunks wouldn´t help you at all: you´ll never be able to edit parts of the image effectively for a seamless re-construction
of the whole image.
Each time you edit close to a border of one image you´ll influence it´s visible relation to the neighboured image - and that results in visible breaks/seams in the final image.
That´s also a problem in retouching the 6 cubefaces of a spherical image . . . That´s why i always point out: NEVER retouch close to the borders
of a cubeface.
Result: better edit the stitched image as a whole.
best, Klaus
