subdiv, attaching surfaces, hole,...

[XorCo]

Hey guys,

I'm a beginner in Maya.. and while I was animating one of my first creations, a bug occured.

When the model is moving a hole appears which it's not expected.
My model is in subdivs and I think it's because I modelled one halve of it and then just mirrored it and combined it instaed of attaching every surface carefuly. So I tried debugging it but it's not quiet working.. can you explain my step by step how I should correct this?

Thank you...

You need to select the two sub-ds surfaces and go to Sub-Ds->attach.

That will make your two object a single one. Then delete the history.

Hello XorCo. Did you use Mirror geometry and set the merge mode to Merge Border Vertices? Give it a try and see if it helps

Where exactly can I do this? :rolleyes:
Thanks for your answers..

Is it not working only at that point?

Reset all your joints. Select them all and set all rotates to 0.
Unbind the skin. F2 -> Skin -> Unbind skin
Click your Sub-D model, hold right click and go to Polygon mode
F3 -> Edit Polygons -> Merge edge tool
Click along where the break was happening, and one of the lines should light up Orangish-Teal. Alongside of it should be a purple line with a big arrow on it. Above or below it might be more arrows. Notice where all the arrows are, those are your breaks. Now click the arrow next to the orange line. Both lines should lightup, now middle click. That edge is now merged. If you had 1 orange line and 3 purple lines next to it it will fix all of them with that one click.

Okay, it works... thanks a lot!

If nothing works, you could delete one half of the object then duplicate the remain section with an inverse scale and attach the objects using subdivision surfaces->attach

EDIT: actually that won't work, you will still have multiple verticies on top of each other.I find the best way to create symetrical object is to first make them in polys. Polys are very easy to combine, and then when you turn it into a sub-d it will be a continuous surface.
