View Full Version : help with model tweaking
two.oh 08-13-2003, 09:19 PM hi all,
i know this question has been asked many times, but ive been trying to tweak an attached ear to a head and i still get these ugly deformations as you'll see in attached picture.
http://www.funktion-studios.com/test_000.jpg
now i would attach a wireframe shot but i dont know how to.
on top of that, im using CPS tools for the head and the ear. i know the trick to fix this problem is to add more geometry around that area to fix the deformations, but i still cant seem to fix it, on top of that if i rig the head, im afraid that the problem might reoccur.
any suggestions? i would look in the search but i dont know what kind of problem i would be searching for.
-thanks in advance

When you attach the ear, you need to make sure that all the cvs on the ear are snapped to vertices on the head. Then make sure you delete the faces on the head that are between the ear and the head. Then merge all the edges around the ear and the head.
If this still doesnt work, you can send me the scene file to judd@backtoback.co.za
Just make sure its in Maya 4.5 or lower, I dont have 5.
Good Luck :thumbsup:

I think u could select the ear and surounding area with your hard edges and just aplly Soften/Harden normals with at least 72 degrees!!!

thats exactly what i did, and that is the result so far.......ive just merged vertices after deleting the faces and smoothed it out as much as possible. if i smooth it anymore, it will look pretty stupid with so much geometry focused around that area.
it wont be very good when i do a mesh smooth in the end i bet. i don't know though....
and i have maya 5 unfortunately, heh.
Dimitri:
i tried that, and tried tweaking the settings off the Soften/harden, and got no results.
thanks for your help guys

I think the best thing for you to do is post a wire frame.
If you've got photoshop or a program a like. Just go into Maya and while you're in wireframe mode, press the print screen button on your keyboard. Now go into photoshop, and create a new document and then press ctrl+v to paste the print screen. Crop the image and save it as a jpg or whatever format you prefer.
Sometimes too much geometry can also cause horrible results, so you might need to actually delete some edges. Just post a wire and it should make things a bit easier!

okay, here it is inside the head, looking out at the ear.
i highlighted the section where the ear meets the rest of the head.
remember, im using cps tools.

Are they still two seperate pieces of geometry? If they aren't, you can actually delete the edges at the major problem point. This will most likely smooth the surface otu a bit. Then you can use the split poly tool to draw the edge back in, since you should put it back.
What you mentioned about adding more geometry is really not the way to think first. Try not adding edges, or even removing edges first. That will usually solve your problem. The same thing might happen when you attach your two head halves together.
Another thing you should do is chek to see if your normals are flipped. You should do this frequently anyway. The easiest way to chek your normals is to turn off the two sided lighting. Any black faces are flipped 180 degrees.

dmc, yea, i know what you mean, but they're two seperate pieces of geometry....
in that case, what do you suggest? i mean, i could hide them with lights and all, but thats not very professional.
all i did was merge vertices, or scale them down so that they're on top of each other.
is there a better way to do it?

Why not attach them? Are you planning to keep the CPS as an infuence for the entire time? I don't think that having CPS attached to the sides of the head and the ears seperately is really the way to go. I mean you will have 4 CPS pieces for just the head, it sounds a little slow going if you ask me.
My advice is to take the CPS off and attach the ear to the head.
What you have to do is select the two pieces of geometry and then Combine. Then merge verts, or edges. That is where your problem is occuring. It's the same way with NURBS modeling. All those little patches have to blend smoothly with each other, so you have to attach/rebuild/detach & attach/rebuild/detach, etc.

that sounds like a good idea.......i thought about it but i thought that i would have to straighten it all out with CPS......THEN combine.....
but i guess this way is simpler.
thanks!

Yeah, you are welcome.
Like I said before, attaching things can be just like working with NURBS.

If you read this link, it kind of explains why you need a good flow from surface to surface, or patch to patch.
