I have opened this issue before, but have since done many "things" and hope
to continue here.
The main problem are black areas that appear in the EXR files while TIFF
outputs seem fine.
I *need* the* EXR* format for 32b hdr, and there is no way around that.
It seems to occur randomly, becaues I have successfully stitched a small
number of panoramas regardless. Those had similar problems but at one point
the holes weren't present, so I just saved the images then.
System A - Desktop:
Windows 7 Pro - 64bit
intel i5
16GB RAM
Nvidia Quadro k2200 - 4GB Vram
System B - Laptop:
Windows 7 Ultimate - 64bit
intel i3
8GB RAM
Nvidia 635M - 2GB VRAM
On system A the black areas occur, while on B the stitching process just
stops. I don't think it gave me an explicit error message. There were some
logs left over after the process failed.
So far I have tried:
- increasing cache
- disabling GPU
- changing blender and interpolation
- adding control points
- removing control points
- photometric optimisation on HDR, LDR, and variable WB (unsure when to
use var. WB, but that's for another post)
- Automatic align/stitch (simple interface mode)
- stitched from any arrangement,
- remap into layers and blend
- exclusion masks on stacks
- inclusion masks on stacks
Things that have been solved so far:
*sun orb becomes grey at centre* - usually one of the images is remapped
improperly, requires checking of individual stacks in preview to notice (CP
errors can still be <1px)
*black patches in preview -* probably intersecting masks. This can be
solved almost realtime by identifying and adjusting masks with auto refresh.
*merged stacks output *- manually merge and output each stack in a separate
project file instead of doing so from the whole panorama. The latter method
drained all of the 16GB of computer's memory and crashed (while the total
of all the TIF files is 3,5GB). I have yet to perform this procedure on the
rest of the stacks (total 5), but am reluctant as it is time consuming and
I have a feeling that once I put all the EXR stacks to be blended it will
crash, hang, fail or something else I won't understand. Anyway, will try
and report back.
I can only use the default engines for fusion and blending - I do not know
how to use or install any external tools.
Because of the file size I can't effectively upload the project files. For
now I will just link the results, and a video clip detailing the procedure
in full, from my dropbox.
