Hello,
Is it normal that i’m getting this error while installing mGear?
It seems to work fine regardless of the error msg… but i still want to double check.
File “C:\Users/Hobbz/Desktop/mgear_5.1.0\drag_n_drop_install.py”, line 594, in load_plugin
cmds.loadPlugin(plugin_name)
RuntimeError: Plug-in, “weightDriver.mll”, was not found on MAYA_PLUG_IN_PATH.
2025-09-04 12:29:17 : Error: unable to load ‘weightDriver.mll’ plugin!
2025-09-04 12:29:17 : Installation Unsuccessful, errors occurred!
What version of Maya? Is the weightDriver plugin compiled for the version of Maya you are attempting to install in? (Check the release/platforms/[YEAR]/[OS]/ folder to see if it exists.
I am on Maya 2025.3 on windows 10
Could you please be more specific with the path :
release/platforms/[YEAR]/[OS]
now a days Autodesk puts everything everywhere in your computer i never know where to look
Ok so i figured out what you meant… i looked in the mGear Folder and from what i can see i have :
mGearWeightDriver.mll
mgear_solvers.mll
But i do not have : weightDriver.mll
Ok cool. So I’ve never used the drag and drop installer. I install via Maya.env.
But in drag_n_drop_install.py, line 29 is:
PLUGINS = ["mgear_solvers.mll", "weightDriver.mll"]
You could likely fix it just by changing it to the right name (there might be other things that need to change somewhere. I don’t know):
PLUGINS = ["mgear_solvers.mll", "mGearWeightDriver.mll"]
And @Miquel when you see this, I guess this is a bug in the drag and drop installer?
Yes! This is my mistake. I never use the installer myself, so this issue slipped under my radar.
EDIT: Here is the fixed version. https://github.com/mgear-dev/mgear/blob/master/drag_n_drop_install.py
As always, you guys are Awesome, Thank you.
