Trying to resolve an error with mgear 4.0.7

[rekindled]

Hey there,
I’m trying to get mGear to work on my friends pc so we can share files. Im on maya2022, python 2.7.11 win10.
He is currently using mGear 4.0.7, Maya2019 and running python 2.7.11, windows10.

When we send over a rig the mesh comes in like this:

and he gets these errors:

file -r -type “mayaAscii” -ignoreVersion -namespace “RIG_SAMURAI_smaller” -options “v=0;” “C:/Users/name/Downloads/RIG_SAMURAI_smaller.ma”;

Does anyone have any idea what is the cause of this and how we can overcome it?

Many thanks!

Usually is not a good idea to open files from a new Maya version in an old Maya version.
Specially 2020 and 2022 added many new things in the rigging area.
My recommendation is to rebuild the rig in the Maya version that will be animated. If you used Data-centric rigging should be a simple thing to do.
