Use AbcExport plugin externally to convert obj to abc

[likage]

Hi all, I am trying to convert objects (.obj) into alembics (.abc)

While I am able to perform this by importing my objs into a maya scene and export it as alembic, is there a way in which I can run it externally out of Maya session? 

Such that I can try running it as a command line or somewhat, by making use of the AbcExport plugin within Maya?

you can just use mayapy, then invoke the AbcExport plugin from there.

Alembic also has a Python interface.

Pretty sure you can do it without requiring any Maya license

Yeah, but then you'd also need to write the code to parse the OBJ file, too. Which, if all you care about is basic stuff (vert positions, maybe normals), isn't that bad... the problem is that there isn't really a firm standard once things get fancier.

Also, the python api is significantly more complex than just invoking the abcExport command.  Cask simplifies things... but if he wasn't aware of mayapy, I'm guessing it's still going to be more complicated than he's looking for.

Hi everyone,

sorry for the delay in reply.

Yes I am pretty much unaware of mayapy, first time hearing this. Trying to search for some tutorials online that may guide me through this.

But if you have any links, please do share it with me :)

Currently I am not sure what is the ideal way to proceed this, as mentioned in my first post - all I have been doing is import obj into scene and export it as abc.

I am trying to achieve this first before implementing any other factors into it. Pretty noob in this aspect.

@Nicholas: I do not even know how to access the python side for alembic!

I keep getting the following error:

ERROR, imageIsFile, can't read `/user_data/custom_scripts/'. Is a directory

File read in  0.024 seconds.

Error: Failed to open IFF file for reading : /user_data/.tmp//maya108600x7fff97d2ea00.iff

Despite loading in the obj plugin, the error ensues.. Not sure why it keeps calling for this .iff file

This is my code:

import os

import maya.standalone

from sys import argv

maya.standalone.initialize()

 

import maya.cmds as cmds

 

def main():   

    obj_file_path = argv[1]

    print obj_file_path

    # Check for path validity

    check_open_path = os.path.isfile(obj_file_path)

    if not check_open_path:

        raise IOError('Input file path does not exists. Please check or make sure that full path is used.')

        return

    cmds.loadPlugin('objExport.so')

    cmds.file(obj_file_path, i=True, type='OBJ')

if __name__ == "__main__":

    main()
