hello sir... I'm doing some serious test with this fantastic plugin .. thank to your great work we can think about accurate crowd simulation..  a couple of questions though: - the attached file shows the cloth and physics global snapshot...the cloth simply doesn't rest and stays up always.. no matter how density I'v giving.. what's wrong with the settings.. - the bug mentioned about ragdoll and physix in the sample files is soleved or not.. ( I'm using Maya 2013 sp2 64bit) - and is the downloadable version ( now) version 1.5.8? mine just show 1.5 in "About Miarmy" thank you in advance Attachments:

1, firstly the cloth in physx 3.0 is still need fine tune, we're optimize it recently, and provide some preset settings soon. the scenario you meet, please try to crank up the first attribute "each step time" and the "solver frequency" should help. I also think the cloth is too light sometimes. we'll focusing on cloth recently after we upgrade the engine~ 2. the ragdoll problem is not been fixed by Nvidia, I hope they can solve this in physx 3.3 But there is a solution can by pass this, make only arms and leg enable dynamics and leave the body controlled by animation can get the best result. 3. yes, the 1.5.8 in download page is the latest one  Merry Christmas! hello sir...

well.... the cloth simulation with cranked up "Each step time " is too slow actually... I think the nature of it is such ..
my question is whether the scale of the cloth object is important (for the same cloth of course )? ( 3 unit length cloth or .. for instance 300 unit length)

I'm not sure in your scenario, but if possible, would you please send me a file so that we can do some further test. by the way, we'll optimize the cloth recently, and do some test and preset attributes setup for it!! also add a wind is a very important also. it can brings some particle based noise on that. well.... the cloth simulation with cranked up "Each step time " is too slow actually...

thankx.. the scene file is a little heavy, I'll simplify it later and send to you for now I think the problem is solved .. the Maya scene file was corrupted so I had to open the file again.. and create the cloth and till now everything is fine.. well, except this... as you see some agents near the cliff ( follow terrain is applied to decisions) start jitterring and some go Up some into the terrain....actully they do not follow the terrain... is it possible that some decisions conflict with each other? or am I doing something wrong....?

Our engine detect the terrain by a vertical ray from sky to ground, I believe the cliff area is not easy to calculated precisely, if possible, please create a proxy terrain without cliff just a boundary there. By the way, why the agents need to go to cliff ?? Best, thankx.. the scene file is a little heavy, I'll simplify it later and send to you for now I think the problem is solved .. the Maya scene file was corrupted so I had to open the file again.. and create the cloth and till now everything is fine.. well, except this... as you see some agents near the cliff ( follow terrain is applied to decisions) start jitterring and some go Up some into the terrain....actully they do not follow the terrain... is it possible that some decisions conflict with each other? or am I doing something wrong....? |
