Having started to play on 3.3.5 servers again, I set out to find a model morpher like tmorph compatible with the patch and came across an old one that still had living links known as Simply Morpher 2. However, upon testing it, it appears to suffer from a major flaw: It crashes the game when you try to actually apply a morph to your character on Windows 10, regardless of compatibility settings. I am going to place the link here for anyone that may have a compatible version of Windows to enjoy it and hopefully find someone to help resolve the issues it presents when used on a Windows 10 operating system.
And here's the source code if someone wants to try to make it work on Windows 10. I'm guessing something needs to be changed in Hook.cs but i dunno what exactly. It's using BlackMagic.
