Hi and thanks.
To make things easier, turn left and right animations are in place. They would look a bit better if we wouldn’t put that constraint on them, but the price to pay would be that the animal would wander away from it’s current spot. With this approach you can turn them as much as you want and they stay in place. Same goes for some of the transitions like “stand” to “sitting” or “lying”, they are made in place even though all the animations are otherwise treated as having root motion, it just doesn’t move when not necessary. This makes the AI part much easier to deal with.
As for your second question, we plan and would love to have these variations via different antlers, we would love to add female/male variations and cubs as free updates. Hopefully people are interested enough to keep us working on them.
Edit: The turns are exactly by 90 degrees with matching stand pose. So if you turn the animal 4 times in one direction it should end up exactly as started. Btw, you can check the animations by downloading for free -> https://forums.unrealengine/showthread.php?94733-Free-Download-Animal-Spider-with-2-meshes-and-66-animations
