Stitcher.exe crashin / comand line is too long

[o.delellis@gmail.com]

Hi,

i am getting errors running stitcher exe,

first it was this error
---------------------------------
>[10/June/2013 21:20:16] - Executing script... (Press ESC to abort)
>[10/June/2013 21:20:16] - The command line is too long.
>[10/June/2013 21:20:16] - Done...
--------------------------------

running this script

alembic_stitcher_shot03.rar

i thought maybe is all the subdirectories i have, so i made it shorter, by moving the abc files, but i got same error. command line too long.

so then i renamed a bunch of files to a shorter file name as per this script:

alembic_stitcher_shot03_c.rar

the 'too long ' error was gone but now i get this other one.

-------------------------

-----------------------

so is there a limit on the number of character a mesh sequence can have for stitcher to work? is it because is a command line thing. like old school 8 characters max?

and i guess, the second error looks more serious..i got 215 mesh files at a combined 8.9 Gb..

any ideas?

i am trying to get extra data to a client on a mesh, and want to test alembic to get velocity/vorticity and any other channels i can get.

thanks in advance

Hi Octavio

You are right, the command line has a limit of characters in most shells. However the stitcher utility is associative:

stitch(a, stitch(b, c) ) = stitch(stitch(a, b), c) )

This means that if you have, let's say 100 files to stitch (chances are the command line will be too long), you will be able to stitch the first 50 files into a temporary file, then stitch the second 50 files into another temporary file, and then stitch these two temporary files into the last one. This is just a workaround to overcome this command line limitation.

The second error looks more serious indeed, Would you please double check that the path is correct? It looks like RF is trying to open a non-existent file.

When you say you got a "combined 8.9Gb", do you mean that you are able to stitch those files? or is it just the sum of all the sizes of the files?

[o.delellis@gmail.com]

oh wow, talk about undocumented

i wll triple check my file path...

8.9GB is size of all the abc files combined, not stitched.

[o.delellis@gmail.com]

so if i keep my file paths shorter can i have more files processed?

[o.delellis@gmail.com]

i moved 20 files to a floder...boom! crash!
so what it does, stitcher crashes..this is the crash info on stitcher

from this scipt

alembic_stitcher_shot03_d.rar

and my file paths are:
input:
T:\FREELANCE\abc\a
output:
T:\FREELANCE\abc\out


could it be it likes UNC? will try moving the files to my c: drive....

[enrique]

It could be a memory problem, maybe the stitcher is trying to allocate too much memory. Could you try to stitch just a couple of files? It should work, if it does not it might be an error with directory access. Can you access the directory where the output file using the command line?

If everything fails, could you send me a couple of those alembic meshes to see if it is an error with the stitcher?

Thanks

[o.delellis@gmail.com]

I copied a few of the frames to my c: drive and i get the same result, crash.

also i tried stitching 3 files, no luck....

aaalso i excluded frame 0, which is empty and i thught maybe this is the issue, but no luck...

i uploaded 5 frames here for you to try to stitch

https://dl.dropboxusercontent.com/u/564 ... meshes.rar

let me know how it goes please!

[enrique]

Hi, I was able to stitch them but I had to avoid the very first frame ("HYMesh_Sh03_008__00000.abc"). It looks like it comes from another simulation because the data it contains is slightly different than the rest.
In the first frame you are exporting:
- uv
- Velocity
- Vorticity

but in the rest you are exporting:
- uv
- Velocity
- Curvature

RealFlow should have printed a message informing about that situation, but it didn't. I still have to fix that.

Please let me know if you can stitch them now (avoiding the first frame, or re-exporting all again with the same parameters)

[enrique]

Oh God, I just realized you're trying to write to a file called "Sh03_008_stitch_*.abc" in your last script!
While is correct to use an asterisk as input, you can't use it in the output file name.

Try this instead:

Code: Select all

import glob, subprocess

# prepare command line
args = ['C:/Program Files/Next Limit/RealFlow 2013/stitcher.exe', '--in']

#get files

for files in glob.glob("T:/FREELANCE/TOYBOX/MACQUARIE_TOOLS/shots/shot_03/abc_008/sh03_008_*.abc"):
   args.append(files)

# rest of the commandline
args.append('--out')
args.append("T:/FREELANCE/TOYBOX/MACQUARIE_TOOLS/shots/final_file_stitched.abc")

# stitch them
p = subprocess.Popen(args, shell=True, stdout=subprocess.PIPE, stderr=subprocess.STDOUT)

# print stitch output
for line in p.stdout.readlines():
    scene.message(line),
retval = p.wait()

i SUCK!!!!!

i need more naps...

it works,BUT it made a 8.45Kb file.....too space efficient!!! considering it was stitching 800Mb (20frames)

tried a few times with less files and same result..

THEN......(suspense)

i deleted frame 0 on which there is no mesh (5Kb file) and IT WORKS!!!!!

ayayyyy....i will try stitching all 200 frames in one go tomorrow morning.
