Hi, 
I don't know what I'm doing wrong but none of the 4 solver node example files do anything when I hit 'play' in Maya- other than the camera panning. Running Maya 2018 with latest trial version of Soup on Mac OS 10.12

Can someone please let me know whether the problem is at my end and how to potentially solve it or whether the new files haven't been tested on Mac ? 

Thanks

Raj

The latest solver node enhances the functionality that you need to change the start and end times

ZC, thanks for the quick response.  Much appreciated.  Other than entering a start frame eg. 1 and end frame eg. 120 in the solver attributes, is there anything else I need to do first because this action causes Maya to hang and become unresponsive.    Tried end frame of even 2 and still same thing happens.

I do not quite understand what you mean, if you can upload your project file, I will help you. Thank you

ZC, thanks for offering.  I am trying to get the example soup files working.  I've attached 3 of the 4 for your convenience.  In these files when I change the scene start and stop from 0 /0 to 1 /200, it causes Maya to hang.  I expect there is something else wrong with the setup in these files for Mac OS.  If you could be so kind to change those parameters such that I could hit play to get it working, I will have a working example to learn from.

Thanks in advance, Raj

I have no mistakes, they run very well. I use the win of Maya2017. Can you use 2017 to open it?

Same problem in Maya 2017.  I suspect it's a Mac related issue ?

Peter : Can you please confirm that the example files have been tested on a Mac ?

Thanks

Yes, this seems like a Mac related issue.
If you switch to DG evaluation of the graph (by detault it is is PE) everything will work fine.
Will take a closer look, but i already suspect that we are running into a specific problem on OSX that will be out of my control.

The example scenes have been updated with the last SOuP release, so if you download them and use the solver ones from there, you won't need to change any settings.

I would allow myself to mention something related to the issue here:
OSX and its third party software ecosystem (Houdini, Maya, SOuP, render of choice, etc, etc) is the worst platform for professional work these days. Too many problems all over the place. If you can use Windows/Linux - go for it.
Just my 2 cents here.

Peter, thank sfor taking a look. Can you please expand on what you mean by "switch to DG evaluation of the graph (by detault it is is PE) " as I'm a bit new to all this and over my head.  Also, I downloaded the example files again and the 4 solver example files are dated Sept 4/5 as creation date and these are still crashing maya. If you have the time, would really appreciate a working file for learning purposes as I really like the look of this solver node.

I see what you mean about OS X but unfortunately I don't have that option right now.

PS, if it helps, here is the point at which it freezes and hangs Click image for larger version - Name: Untitled.jpeg, Views: 10, Size: 215.53 KB

Ok, an update...I managed to get 3 of the files working by switching to DG in animation in preferences.  Thank you very much for that.  The file that still hangs is solver_organic_growth.ma.  Any ideas what is different to resolve that one ?

Glad to hear you figure out most of the problems.
Will check later today that bad boy and see what is bugging it.

The solver_organic_growth.ma scene works fine here.
Maya2018 (VP2, DG eval mode) and OSX 10.11

What version of Maya do you use ?

I'm using Maya 2018.  Have had same problem on Maya 2017.
OSX 10.12.6 Sierra   Using DG Eval mode in animation.  Found a VP2 setting and set it (can't find it again !!) but it does not make a difference. the scene hangs as soon as I put in the end frame in the solver node.  If you have the time, would be great to have it working or perhaps a similar scene to test. Want to analyze to learn process.  Thanks in advance.

Ok, tried everything i can think of to break it in Maya2018 and cannot get it to crash or misbehave.
Can anyone else confirm the problem RajSoup is having ?
Trying to understand if this is a widespread issue or something isolated to his HW/SW configuration.
Thanks.
