:shrug:

I am having trouble trying to create a cloth material, i.e. a shirt.

The problem is when trying to create a closed curve. I click all the necessary procedures to do so, but I keep getting a warning message saying "can't create a panel needs a closed curve loop".

I look in the attribute editor and in the section nurbs curve history and in the form box, it should say closed, it doesn’t it either says open or periodic.

How do I close the curve? It’s the only thing I can’t figure out what to do. Please help

MJM !

Each edge of the boarder has to be separate pieces but they have to form a closed shape, so no open edges.

If you dont understand then open up the sample cloth files that came with maya so you see how they do it.

Hi!

I have the exact same problem. So far I havent seen any good cloth-tutorial for maya. Anyone knows where I can find one? (Don't say the tutorial from Using Maya, that's the one i've tried so far without success).

I've been following the tutorial from Using Maya, and I still can't get the curve to close. I've used the snap to grid and edges tool to help, but still no joy. I've also tried using the open/close tool.

Is there a procedure I'm missing in anyway? Or a button.
I'm very new to Maya, so the simplest things I may have missed.

you usually do your cloth in patches that are formed by 4 (or more) seperate curves.

to be sure you curves start and end on the other used curves you should use the curve snapping functionality.

- create curve1 (random)
- before clicking the first time for curve2, press and hold the "c" key. now drag along your curve1 holding the left mouse button. you will see the first cv of your curve wandering along curve1. drag to the very end of curve1 and release the mouse button and then the "c" key. now your beginning of curve2 lies 100% on the end of curve1.
- repeat for the other 2 curves and repeat the snapping for the last curve to bring it on the first curve again..

now you have 4 seperate nurbs curves, that build the needed closed curve loop.

have fun

cheers

Whoa alexx. I was pulling my hair out with this problem and finally someone made sense of it for me! Yeehaa!
This method of making curves works. I can now build panels.

Cheers,
