Problem at simulating

[vmarines]

Hi

I am using MAYA CLOTH and MAYA 6.0

I can tell you that yesterday I follow the tutorials in the www.learnigmaya.com and the section http://caad.arch.ethz.ch/info/maya/manual/....fm.html#178443 in the section of the cloth and fur and follow the one for the tablecloth to going step by step as a little boy : )

Ok when I finish the tutorial and play the time slider to simulate I got the next error message at the 2nd frame

Warning: Cloth solver, cpsolver1, is having difficult solving the simulation, aborting !

Warning: Cloth solver interrumpted, going back one frame

I follow that tutorials Because my models in my scene are too small, the dimension I am using are 1 cm each square on grid, and I do not know if the size is something to do when you are making garments, I have a little bell and want the ribbon pass trough the little ring it has on top and then drape the ribbon over the bell and the table where the bell is

But the sizes for the bell are like 0.2 cm tall and the ribbon is 2 cm long, the size is something to do?

Thanks very much in advance

How can I attach a JPG picture to you can look at it?

When the simulation stops at the first frame and you got the warnings, you must open the attribute editor and go to the solver tab, then change at the bottom the adaption control to no action. This prevent, that the simulation stop when the calculation is longer than the solver thougt it should be calculateted.
For the second problem you have also in the solver tab the attribute solver scale. This attribute is the multiplier for the cloth simulation between the units in your maya scene and real units. So when perhaps a character was modeled with a hight of 30 cm and the character was in real space 180 cm the the solver scale is 6. So when your ribbon is 2 cm long in maya and in real the ribbon was 10 cm long then you must set the solver scale attribute to 5.

I hope this help

thanks bhone to take time to answer

let me tell you, that during these days I have made some testing regarding this issue,

I figure out, my own opinion is that maya doesnt work
very well with models too small (collision and garments), I do not know if it is a problem with the solver or the way it uses the solver scale parameter,

I have to increase the size of my models at least 2 cm in real world size, based on the grid units, then a make the ribbon like 6 cm in the maya units, then I use to sclae the solver to 15 to have the cloth behavior as 60 cm, it works pretty well.
the other important thing to work with is the resolution for the stitcher I have to set it to 800, I did not set the resolution factor, I set it to 1 in the panel atribute.

anhoter important thing and not logical for me, is that I have to change the normals of the nurbs table in the direction of the gravity (-y) so the ribbon collide with the table, cos otherway the table pull the ribbon trough it.

I learn is better to make slow increments or decrements in the collision objects's offset parameters and try it to set the final resolution in the stitcher node because if you set the final resolution and not adjust the offset , the drape could not behave the same.

Ok thanks, I will move to the adjusting the cloth using constraint and move it trough the bell ring to have the final position of it over the bell

let you now

we are in touch
