Okay, here's an archive with 2 files: an FBX model with a skeleton and a TGA – a texture map. You can apply the cyclops' diffuse texture to it; it should match pretty well (about 90%), so you won't have to redraw the cyclops' head and teeth. However, you'll need to redraw the body and appendages... I checked the files, but if I made any mistakes, let me know.

Ah, I see...
In *Rome 2*, I once transferred the animation of a human to the animation of an elephant, so that there would be two people on the elephant: a driver and an archer. Well, I'm not a 3D master, and I got tired of doing it because, at least in *Rome 2*, as far as I know, the skeleton needs to be a single whole. If you take the animation of one skeleton and attach it to the root bone of another, the animation gets distorted. I had to use some tricks... Well, there were about 30 animations to connect.
