Well, this took a while... I just didn't have time to convert it to python 3...
But now it WORKS with Maya versions that require python 3. I tested it on Maya 2023, but it should work on Maya 2022 and newer. For all users that are on the earlier Maya versions I left old version that works on python 2 in the same folder. There is explanation how to use old version in lookdev_kit_install.txt
You can download it from MY STORE FOR FREE
Expect bugs, but I hope it works fine :)
