I'm wondering that I haven't posted this yet here. :) Many of you probably already know rapidTools, but for those ones who don't: I created many many tools over the years and I created a package from them. It's fairly easy to install, just drag and drop the mzp. You can download it from here: https://rapidmxs.com/store/…
Up to 2012+ Theoretically most of the scripts are working properly on older versions of 3dsmax. Since they are maxscripts and not plug-ins they don't have to be recompiled.
I made a polyModOp library to make converting tools made for editable poly to edit poly modifier easy, depending on whether the scripts in the mzp are encrypted or not, you can do it yoursellf or ask @pi3c3 nicely to consider doing that.
