I made a plugin for 3ds Max - Radially.
It is a pie menu editor for 3ds max that can handle up to 12 3ds Max actions actions per pie menu. Here is a link
to the demonstration video. Radially is still in active development, but its most valuable features are already implemented and I am ready to get some feedback on it.
There is more info available on the Gumroad
page of the product, so if you are interested - check it out!
