Just a little post I made for more info on these models. As you can see how it looks without any disruptions to the 3D mesh. Note that the topology isn’t the best, as I was more worried about optimizing the polycount than it being perfect quads.
The reasons the eyes ‘look at you’ when facing near the back is due to how I managed depth on the topology. As there’s no actual animation going on there.
I tend to keep these models under 1000 tris, and even than, it’s a bit too high-poly for early 3D games.
This was originally posted from my blog, I merged both gifs into one, and I also fixed the looping issue.
