Thanks!Lookin' better than ever! i hope you continue on this addon, it's got potential!
I also completely forgot something I wanted to point out and forgot to beforehand:
Here is the SADX running animation from the side:
Frankly, I think it looks terrible. I think from the front and back it's okay, but those same frames from the side look really robotic and wonky. Even though it's more effort, I'm very much happy with taking the time to use the SA2 models and then modifying those to more resemble the Advance animations.
