DSimmonds Posted July 11, 2016 Report Share Posted July 11, 2016 Hi All, Has anyone else encountered a problem where the identified period of a loop is not the actual looping point? I have been scratching my head over this for a few days and gotten to the point where I think the stiffness value is having something done to it before it is fed into the equation. I have already worked back to the equation that generates the displayed period (which I then found in a forum post).. Leaving other variables at 1 for simplicity, I'm finding that changing the stiffness value results in loops as below: Stiffness Period Actual Period 0.5 5 ~15 (give or take a few ticks) 1 10 30 2 20 ~32 3 30 ~39 4 40 50 5 50 ~58 6 60 ~68 And so on. I've found there is a decreasing value which approaches 1 as the stiffness value increases. But that's about where my ability to pull this apart ends. The difference factor I have found does plot a pretty neat curve [3, 1.6666, 1.3333, 1.25, 1.17, 1.141667], but I can't quite bring it into something I can use to predict the actual period. If there's any suggestions out there, I'm all ears. (incidentally, GrowFX version: 1.9.9 sp2) Kind Regards, Quote Link to comment Share on other sites More sharing options...
Eduard Posted July 11, 2016 Report Share Posted July 11, 2016 Hi DSimmonds, Please send me your scene file where you got these results... Thanks! Quote Link to comment Share on other sites More sharing options...
DSimmonds Posted July 11, 2016 Author Report Share Posted July 11, 2016 Hi Eduard, Thanks for the reply. Please find attached a simple test scene. I've stripped it down to bare bones, but if you need it in another version/format, please let me know. Kind Regards, Daniel WindLoop_GrowFX_TestScene.max Quote Link to comment Share on other sites More sharing options...
Eduard Posted July 12, 2016 Report Share Posted July 12, 2016 Hi DSimmonds, Yes, you're right, there is some inaccuracy. This is due to the fact that you've the System unit scale = 1 meter, and if you make your scene with System unit scale = 1 cm or 1 inches, then the problem will be solved. Please see my example: WindLoop_GrowFX_TestScene_2.max Of course, we'll try to solve this issue programmatically. Thanks for your bug report!

DSimmonds Posted July 13, 2016 Author Report Share Posted July 13, 2016 Thanks Eduard, That has resolved that issue. On to looping some trees! Regards, Daniel Quote Link to comment Share on other sites More sharing options...
