Pre custom step geo failing

Support
#1

Hello!
Banging my head against the computer…
I am trying to get the pre script for loading my Geometry working.
I have been looking for any typos but can’t find any.
I set my maya.env path with the following:
MGEAR_SHIFTER_CUSTOMSTEP_PATH = /Users/todd/Rod Dropbox/thor can/maya/projects/grays/custom_steps

The path to my scripts and Geo are:
/Users/todd/Rod Dropbox/thor can/maya/projects/grays/custom_steps/scripts/pre/import_geo.py

/Users/todd/Rod Dropbox/thor can/maya/projects/grays/custom_steps/assets/geo.ma

I add the import_geo.py file to the guide settings and get the following faliure on build:

GEAR version : 4.0.7

The code for the import_geo.py is unchanged to from the Github file.

the error is RuntimeError: File not found. print the path to check if the path resolved is correct.
print(os.path.join(path, "assets", "geo.ma"))

#3

It might be because of the spaces in the path. (I don’t know if that is supported or not. But worth checking.)

#4

Thanks a ton for the help!

I simplified my path to my User folder. This removed the spaces.
I updated the maya.env and get this when I check it:

getenv "MGEAR_SHIFTER_CUSTOMSTEP_PATH"; // Result: /Users/todd/custom_steps; //

I run
print(os.path.join(path, "assets", "geo.ma"))
which returned:
# Error: NameError: file <maya console> line 1: name 'path' is not defined #

building the rig gives me this now:

Well, that “path is undefined” is because you’ll still have to run the first line to declare what path is:

path = "\\".join(os.path.abspath( os.path.dirname(__file__)).split("\\")[:-2])

But you have to run that in your build script. If you just try to run it in Maya script editor, it won’t know what __file__ is.

Try putting that print line in your build script, before the importFile, then you’ll see it in your build log, just before the error:

def import_geometry(self):
    path =  "\\".join(os.path.abspath(
        os.path.dirname(__file__)).split("\\")[:-2])

    print(os.path.join(path, "assets", "geo.ma"))
    pm.importFile(os.path.join(path, "assets", "geo.ma"))

The “build_data” error might be happening because of other errors. So I’d ignore that for now, unless it doesn’t go away once you fix the path problem.

Thanks!
Added the print line to the build script and it prints “assets/geo.ma”
Does this mean that the error is not the path problem but something else?

I got the path working! THANKS.
I was also having a problem with the fact that I was running an educational version and it was getting stuck on import when maya asked to ok the educational terms.
Again, THANKS!!
