RTF is a global modification that replaces all towns in the game.

Okay, to be honest, I don't really understand anything yet....

I have no idea, it's clear that all these exports through a million programs are breaking the model. If I open ANY FBX file in 3D Max, nothing is broken; I showed videos....and all the animation is baked....

I'll take a look – I don't know what the PSA format is.

I think I didn't make the idle animation first.

I checked, it says that the PSA format is a Photoshop format? How can that be? Animation in Photoshop format????

Here's what I did: I extracted all the animations from the game, converted them to 3D Max format...then I opened all the animations one by one and saved them to a file, then I opened the Zloboglaz file, copied the saved animation (to the animation keys), then I selected the bones and the basic Cyclops helpers (analogous to bones) and baked the selected elements into an FBX file along with the mesh....
