exportSelected in cmds.file

[Mahmoodreza Aarabi]

Hello guys

Please take a look at this and guide me.

Situation:

We have a FinalModel that is referenced in a scene for rig. In the rig scene, meshes get skin and rigging stuffs.
after that i want to save the scene using code (Here using Pyblish’s Plugin) that use this code:

cmds.file(path,
      force=True,
      typ="mayaAscii",
      exportSelected=True,
      preserveReferences=True,
      shader=True,
      expressions=False,
      constructionHistory=True)

Problem:

The code will save the selected group in a new file and their connections in a new .ma file fine, but when we open the scene meshes does not show their shaders and just show us wireframe, while, meshes have materials connected to ShadingGroup.
This event happen when i export selection manually with maya menu.

make sense?

thanks

this may work 

select the objects or top group

cmds.file(rename=path+filename.ma)

cmds.file(type="mayaAscii",exportSelected=True,preserveReferences=True,shader=True,expressions=False,constructionHistory=True)

Hey Sumant

thanks for answer.

i test rename flag of file, but it does not give path, just can i give it a new name, i think to a new way to use save flag instead of exportSelected.

but i want to know why export selecting in maya ruin our shaders, you know?

Hey again
i test this snippet but this does not work:

from maya import cmds
dir_path = 'C:/test/test.ma'
cmds.file(rename=dir_path)
cmds.file(s=True, f=True, typ="mayaAscii")

and gave this error:
# Error: RuntimeError: file <maya console> line 3: An invalid path was specified. #

any idea?!

I think using exportAll will solve the problem

cmds.file(path,
      force=True,
      typ="mayaAscii",
      exportAll=True,
      preserveReferences=True,
      shader=True,
      expressions=False,
      constructionHistory=True)

If I recall correctly, windows paths uses \ instead of /... try replacing the path by: dir_path = r"C:\test\test.ma"

Notice the r character before starting the string, this means it's a raw string (\ is a escape character), if you don't want to use a raw string you will need to use something like "C:\\test\\test.ma".

Cheers!

You are right, but this is not affect the code

rename just get new name not new path

i used exportAll flag and it works fine

btw, thanks for the point
