TWO PROBLEMS; direct.task and Attribute Error

[Daviderr]

I have two problems,
when i start mesh tool it says:
Warning: filter 'viewer' disabled because of ImportError: No module named direct.task
Warning: filter 'collada_viewer' disabled because of ImportError: No module named direct.task
Warning: filter 'pm_viewer' disabled because of ImportError: No module named direct.task
Warning: filter 'save_screenshot' disabled because of ImportError: No module named direct.task
Warning: filter 'save_rotate_screenshots' disabled because of ImportError: No module named direct.task
Warning: filter 'save_bam' disabled because of ImportError: No module named direct.task
even if installed last version of Panda3D.

And when i try to load an obj file and simply write it it says to me:

Traceback (most recent call last):
File "/usr/local/bin/meshtool", line 8, in
load_entry_point('meshtool==0.3', 'console_scripts', 'meshtool')()
File "/Library/Python/2.7/site-packages/meshtool-0.3-py2.7.egg/meshtool/main.py", line 89, in main
collada_inst = inst.apply(collada_inst, *arguments)
File "/Library/Python/2.7/site-packages/meshtool-0.3-py2.7.egg/meshtool/filters/save_filters/save_obj.py", line 30, in apply
save_obj_util.write_obj(mesh, rel_mtlfilename, f)
File "/Library/Python/2.7/site-packages/meshtool-0.3-py2.7.egg/meshtool/filters/save_filters/save_obj_util.py", line 107, in write_obj
f.write("usemtl %s\n" % boundprim.material.id)
AttributeError: 'NoneType' object has no attribute 'id'
and when i open it with some OBJ Viewer like MeshViewer the new obj file has only vertices and no faces.

Thanks

You can ignore the warnings. Would it be possible for you to post the .obj file?

I think b52501d should fix the second problem. Could you run from master and confirm?

Thanks for your support, ok i modify the code following your advice now:

MacBook-Pro-di-Davide-2:~ DavideMorgagni$ sudo meshtool --load_obj /1.obj --save_obj /12.obj

TypeError: zip argument #1 must support iteration

And the output is still an obj with only vertices and an empty .mtl file.

Can you try this:

meshtool --load_obj /1.obj --medium_optimizations --save_obj /12.obj

or at least this?

meshtool --load_obj /1.obj --generate_normals --save_obj /12.obj
