First, I have noticed that there are hard edge seams along the cuts of the UV map which are only visible ingame and not in any modeling program. I am pretty sure no other game that I have played does this. Is there any way to get rid of it? Or at least a method to make it not so obvious? It is especially annoying on organic meshes (such as the pig below). I haven't ever noticed it in Vanilla Bf so I thought maybe there is a way of getting rid of it.
Here is an example of what I mean. Look at where the limbs attach to the torso and around the face.


Next issue is horse(as a vehicle) animating. As you might have seen, all other mods that have horses in them(Civil War mod, Western Wars, FH:SW, etc.)have really ugly animations which just use rotation bundles. Currently the Siege mod horse doesn't have any animation at all for movement. The legs are badly covered up with a heraldic "sheet" of sorts. This isn't really a sufficient look. After looking at Apache's banana and Mario, it appears that a realistic animation is very plausible. How complicated do you imagine it would be to animate each joint on a horse's leg?
If true animating doesn't work properly, I have another idea in mind, although it is a little complicated and might not work either.
I would like to have a new player model put ingame for each team. I know this is indeed possible, and our team's coder/animator might learn how to rig one some time when he is not busy. Realistically, soldiers of the Hundred Years wars had skirts that went over the upper part of their legs. Would this cause problems for animating the legs? Here is a picture of what I am talking about.

Also, is it possible to have more than one player model per team? I believe in Forgotten Hope there is a code that randomly chooses one of two or three when you spawn to add more variety. Could you choose your player model by the kit you spawn as?
Next, can you attach projectile "bullet holes" to player models and vehicles? The bullets holes in this case are arrows, throwing knives, and a fire effect + an arrow. Basically, if an arrow hits a player or a wooden vehicle I would like for it to stay in them. And when firing a incendiary projectile at a wooden vehicle, such as a catapult or battering ram, could the fire stick and deal damage gradually to the vehicle even if it moves?
That is all I can think of right now, but I am sure there is more I have forgotten.
Our team currently consists of only three often inactive people, so any help would be greatly appreciated.

Thanks.
