cloth ? - 06/20/18 23:02

Hi guys!

Can anyone else get cloth example from samples folder working? For me it just doesn't get created, PVD doesn't show it as well. I wonder why it's not working. I even installed PhysX System software but it doesn't fix the problem. I remember that it used to work out of the box, but maybe before the 'latest' update?

Best regards!

Just tried clothdemo from samples folder with your .dll and it works! But it crashes on exit/close. In my other projects with cloth it crashes too.

Never used -diag before, I simply added -diag in SED Preferences, under Command Line Options and then clicked Debug Run.
If it's needs to be done differently, just let me know how and I'll do it man. Thank you very much for helping out!

Thanks, rename the old ackphysX.dll to ackphysX_old or something like this and try again.

Re: cloth ? - 07/21/18 18:44

Now it crashed SED (if I run in debug mode, in 'run current script' mode, it simply crashes as before.

Renamed old 'ackphysX.dll' to 'ackphysX_old.dll' and placed new one in 'acknex_plugins' folder.

Re: cloth ? - 07/21/18 19:11

Please rename it without the (.dll)

Posted By: rojart

Re: cloth ? - 07/21/18 20:45

just for clarity, you need to open one ackphysX.dll, but not two at the same time.

from your log file:
...
acknet.dll opened
ackoal.dll opened
ackphysX.dll opened
ackphysX_old.dll opened <- Wrong!
...

Re: cloth ? - 07/22/18 00:57

Ok, removed .dll
Here is log

Re: cloth ? - 07/22/18 09:06

any crashes?

Re: cloth ? - 07/22/18 13:05

Sorry, yes. Crash is still there.

Re: cloth ? - 07/22/18 15:00

ok, that's normal because of my different dll, but this is not the issue.

Probably after the change of "PhysX System Software", the GPU acceleration is no longer working, I'll check why.

Now you can check the same effect with the old ackphysX.dll

1. Make sure to use the old ackphysX.dll in acknex_plugins folder.

2. For some debug run the NVIDIA Control Panel and check "Show PhysX Visual Indicator" under "3D Settings" Menu.

3. From task menu "Configure Sorround, PhysX" change the PhysX Settings.. to CPU.

Now the cloth simulation should works without GPU acceleration.

p.s.
Even the GPU PhysX 3 of cloth simulation, also does not work.

Thank you for the answer, rojart!

Re: cloth ? - 07/22/18 18:48

All this means (as far as I understood), that cloth in acknex (physX plugin) is always simulated on GPU. If so, then 'NX_CLF_HARDWARE' flag makes no sence.. Is there any way to set CPU to default and make GPU simulation only with 'NX_CLF_HARDWARE' flag set ?

Greets!

Posted By: rojart

Re: cloth ? - 07/23/18 18:12

Take a look in the ackphysX.h file.

Code:

var CLOTH_DEFAULT[40] = 
{
...
// Flag bits.
0 // NX_CLF_HARDWARE is set automatically, depending on your GPU (see above)
...
}

Therefore this function in the old dll will not work, but with my new dll should work.

Code:

cloth options[37] &= ~NX_CLF_HARDWARE;

Re: cloth ? - 07/23/18 23:50

Sad, I hoped there would be easy way out, simply by 'unsetting' that flag before creating cloth. Thank you for your time and help, rojart!

Re: cloth ? - 07/26/18 17:11

Gladly, I found the issue!

rename the nvcuda.dll file to nvcuda-dll from C:\Windows\SysWOW64\ folder.

Now the clothdemo should work in the CPU mode.

Great to read this!

Thank you very much, rojart! It works now.

Thanks, but it's really annoying when the old Nvidia libraries are forgotten.
