Blur resolution with huge 228 gigapixel

I have a 228 Gigapixel.
When I export it with multiresolution, the zoom is completly blur. (9 levels of multires)
I've tried to export only an extract of one Gpx and it's sharp. (7 levels of multires)

This is the difference in the viewer
- Left :228 Gpx
- Right : Extract of 1 Gpx from the 228 Gpx

If I check the tiles of the 9th level, they seem to be sharp. The size of th 9th level makes well 228 Gpx.

Screen copy of tiles 9th level 512x512
Tiles are sharp

The problem should come from the xml file or the viewer...

If I let maxipixelzoom to one, I can't zoom to the maximum level. If I set it to more, then, it becomes blur.
It's as like if it was not possible to access the highest levels.

Here are my settings.

multires.config

# multiresolution settings
multires=true
tilesize=512
levels=auto
levelstep=2
maxsize=auto
maxcubesize=auto
leveldownload=auto
# compression settings (note - no jpegoptimize for extreme big panos, this could cause too much memory usage during building)
jpegquality=95
jpegsubsamp=444
jpegoptimize=false

basicsettings.config

# image filtering and compression settings
filter=LANCZOS
jpegquality=95
jpegsubsamp=444
jpegoptimize=true

Tests are quite long, it takes me 24 hours to export the 228 gigapixel !

Thank's for your help.

Hi Klaus.

The problem is that I have 70 Go to upload before. I would prefer to be sure before to send it.

Can you see something wrong here in my xml ?

I've tried with 10 maxipixelzoom, but it makes a numerical zoom...

<include url="skin/vtour-intro.xml" />

<!-- view settings -->
<view hlookat="0" vlookat="0" maxpixelzoom="2" fovmax="10" limitview="fullrange" />

I haven't desabled it. That was made automatically by the droplet.
I have desabled it in the .xml and it works well !

My 228 Gigapixel is fantastic now. Thank's to KrPano.
I'll let you know when it will be online.
