Ok need help eyelid/eyes!
Getting into some tricky stuff... ok my model is an anime type character.
Since its an anime type character the eyes are shaped difrantly. first issue i need to make eyes and the spheres don't work well do tot he fack the sphere don't take up the whole eye scket and if i try to make it bigger it clips. i need a perfectly round sphere so i can animate the eyes with ease. are there othere ways to make eyes?
next:
Eye lids, i need techniques to do eye lids that will be able to be animated. I am shooting for seemles eye lids that a> look like there part of the mesh, or b> are part of the mesh.
I tried clusters but that WENT TERRABLY WRONG. as i said befor the eyes are shaped difrantly. thus this makes things very dificult... and i'm kinda shooting for a profesional look

right now the mpdel don't even have eye sockets.

side note: the model was done via the low poly>smooth technique. i will also give you a front view sketch of my model

Hmm,
I think I understand your dilemma.

My first question is: Why use sphere anyway? If your going for an anime look, then I think you could get away with a quadrant of the sphere or less. Ref. Fig a.

Second: Why not just model the eye lids from the mesh? Then after you are finnished modeling, but before the smooth is applied:
1. Duplicate the low res poly mesh. Apply smooth to the duplicate.
2. Then when it comes time for set up, use the high res mesh for rendering, and the low res one as a wrap deformer("Fly by wire" of animating). You can use the clusters on the wrap deformer, or use blend shapes(the later is the easiest)

Wrap Deformer: Using a low-res poly wire frame to controll the deformations of a much denser hi-res poly mesh. This concept is similar to how you use CV's to controll a NURBS mesh.

Hope it helps:)

The only problem you have is with the eye-lids.

On a mesh, the eye lids should move over the eyes, and so you will have to group the mesh-points that represent the eye-lids and manipulate them in the usual manner...

The eyes themselves only need to be textured white(as part of the mesh), and then for the pupil itself, make a small sphere to position them.

I suggest looking in the Rei ayanme threads for better guidence on this one...use the key words 'Neon Genisis Evangelion' on this sites search engine to locate them. One chap has done a Unit-01 pic and he put a link upto another artist who made good model-pics of Rei and Auska. Its worth the hassle of finding them!

I'm doing eyes myself at the moment, so I'll see what I can come up with...

Sorry bout my last post, but crown royal is a harsh and cruel mistress.
I think you should listen to boone. But if you are interested in wrap deformers, do a search for "wrap" in the maya help index, and it'll show you how to use it. Wraps make animation easier cause your not dealing with the high res mesh in real time, only when you render.

also look up blend shapes, it is also called morphing, or morph target. Blend shapes are an easy way you can controll facial animation. you can also use them to correct deformation issues, but that topic is really advanced.

Do a search on these topics and you will be happy with information.

Oh yeah. Thanks for reminding me, Noktup. Morphing. Yes, what I did in Real3D was made a mesh of the face, saved it.
Then I made a copy of it and changed the copyed mesh to form the desired expresion.
I'm sure you can now do this in any modern 3D package, but first you load in the first blank-expression mesh-face. Call it 'Face-1' or whatever...then load in the second new-expression mesh-face. Call it 'Face-2'.

Now you'll have to see how your 3D App does this, but in a nut-shell, have 'Face-1' morph into 'Face-2'.

String different face-meshes together in this manner and you can consider yourself a true animator! :cool:

Good luck in your work!

In Maya they are called "blend shapes" and they are rediculously easy to use. You should try to find a tutorial, cause they can some times be a little confusing.

**Make sure you keep the targets, dont delete them or remove them from the scene unless you do it like the pros(2nd paragraph).**

When skinning the head(after the blends are finnished) dont forget to skin the blends allong with the head, this ensures the blends will interpolate properly when the head is rotated or translated. If you dont skin the blends along with the head, and the head is rotated, the blends will try to "force" the verts/CVs that were adusted back to the physical location of the blend pose, while the head is still rotated. This can look nasty and be tough to work around.
The pro's only make blend shapes for the face, thusly, when the head is rotated the blend shape is rotated along with it, and when you key a blend, it forces the verts/CVs to the blend's position, which rotated with the head. This method is acheives best results, but requiers a more in-depth understanding of maya/ blends and surface tangency. All tutorial are done this way.

As confusing as this sounds, its really quite easy. You just have to get past the crazy new words those cats at alias/all other software dev companies come up with.

PS I'm good at confusing people, so dont feel bad if I loose you, just ask... and knowlege will be dropped on you dome!

Hope it helps:)

Yes - Maya. I got the PLE on the front of 3DWorld two days ago...shame my computer won't run it!

Say, noktup - is it worth buying a new computer to use Maya-PLE?

OH HELL YEA!
Ive use maya, 3dsmax and lightwave, and the all around winner by far is Maya. Its just wether you can afford it or not. All you need to run maya is anything above a P3 450 and a good g-force, or the new radeons. I 've never, however, used Maya PLE (personal license edition?????) I will only use no less than maya compleet, which might actually be the same thing, just marketed differently. The unlimited license, however, is the best cause you get all the nice extras like dynamics and fur.
when you do get around to buying a new box, I suggest you do great reaserch into what hardware to buy, cause if you get all the right stuff(ie mother boards that are ultra reliable), then it will greatly increase your ejoyable experience using maya, not to mention set your work flow on a steady/strong pace. The right vid card is also crutial, because if the card has issues, like some brands of g-force, with certain openGL exensions, like overlay planes, you'll have a very annoying maya experience.
Usually cards designed with"digital content creation" in mind work the best.
Sorry about all the run-on's:(

Happy box hunting:)

Wow! Thanks for the info!

Just one more thing - If I know how to use Maya, will it likely land me a job? Or is it an up-hill struggle even then?

maybe... but most likely if it lands you job it would be in the cinma field. ( with an exception of Pixar, they use there own in house software called Marianett )

Nothing is a shoe in like Skizz-ills. Plus its more of WHO you know then what you know. Start networking now, and most companies dont expect you to know any more then whats on you demo reel.
You just have to keep at it untill you are noticed or make your self known. Right now its hard to find a job, I my self have been looking for over two years( i just dont know any one:)
any how keept up the good fight!
