I have decided to share the complete tool sets I have been using recently. I made these so I had easy access to all the scripts I have both made and acquired while working in Max. As you can see there two different tool bars each one tailored towards a different game engine.
The links to download them are underneath respective images. To get them working in 3DS Max all you need to do is unzip the folder and run the 'Tools' maxscript from inside 3DS Max.
Some of the features, particularly on the UE4 tools set, are still work in progress but are at a working state how they are now. If you do come across any bugs or think of any additional features that would be useful to add to either of the scripts then please contact me using the form below.
