If the head is directly connected to the neck, it potentially produces problems when the head is rotated. Ordinarily, the head is a separate mesh, and only one vertex is connected to the rest of the body (it's roughly under the chin).

Like here:

The same is true for the rabbit's head.

So you might want to test this out to verify that it's working as you intend once you've got the thing "rigged".

The underlying issue is that each vertex is associated with exactly one bone, and there are no weights. Consequently, if the head is rotated, all the associated vertices are rotated along with it 1:1. So you might end up with neighbor polygons crossing over and things like that, that leads to flickering and other visual artifacts.
Edit: Worse even, the part of the neck that's connected to the back of the head will stick out if the rabbit looks down. Weighting would solve that, but there is none.

I know, it sucks, but you might have to work around this flaw in some way.
David just made a stump for the neck that's high enough so that the head never exposes the flat part on top, no matter how it's rotated.
It looks best if the connecting vertex is somewhere near the rotation pivot of the head bone.

Thanks for the input, but my goal is specifically to not make a masculine looking body, to allow for more believable female characters.

I think alpha-mapped fur will not be possible since the Lugaru engine does not support alpha levels other than completely on or completely off, and i'm not sure that's even possible to do with objects other than trees/bushes. Also the model needs to be able to have clothing in the texture, and so if I had alot of scruffy fur that would then be what the clothes look like on the body.

I'll experiment with alpha textures a bit more though, will get back to you on that.

This looks really great compared to the original.
Anyone knows the polygons count for the model in Overgrowth?

Yeah, you're right, will have to try rigging this as soon as possible, to see what happens.

I already know that I will probably have to simplify a few of the joints to make them work better with the rigging.

Yeah; the arm is another candidate:

I can't seem to find that data.
You said how many there were on the Lugaru model, however.

Bleh, my appologies, too tired to read correctly.
Here are the stats of the models currently used in Overgrowth:

IGF_Guard.obj:
5152 polygons, 7750 edges, 2608 vertices

IGF_RabbitCiv.obj:
4561 polygons, 6864 edges, 2313 vertices

IGF_Turner:
4748 polygons, 7133 edges, 2406 vertices

IGF_Wolf:
4691 polygons, 7062 edges, 2381 vertices

Keep in mind that these are not the final models, just stand-ins for now, until dynamic fur and clothing is implemented

Are you nearly finished with the rabbit model?

I'm not much further than my most recent update.

Things I Still have to do:

- Finish the ears.
- Test the model rigged in the Lugaru engine.
- - Adjust the model accordingly to work with the engine's rigging, this could take a while.
- Texture the model, this will also take a while.
- - Bake Ambient Occlusion/ Simple Shadows
- - Draw fur pattern
- - work on some clothes
- Clean everything up.

... And some other cool stuff

:shock: That's awesome for being just temporary models.

Let's just say that I'm not that experienced in this perticular area, and that I'm easily impressed :D
