Wind Animated Plants created in SP7 causing problem in SP8


Recommended Posts

I created a plant and 'wind animated' it in SP7. But recently I installed SP8 and there's a new feature Amplitude Multiplier (Which is cool BTW) but I forgot that it would affect my animation because it has a default value set already which changes my animation to something different. Now I have many plants and trees created in the older version. Is there any way I can disable the Amplitude Multiplier effect in those? or Do I have to set its value manually to something (zero I guess?) to get my old animation back?
Thank you!

Maybe it's not about the default Amplitude Multiplier Value because I tried to change it but can't get the old result back.

 

Hi Faisal,

 

Yes, we changed the calculation a little bit to make the branches movement more smoothly.

Can you send me this scene file? 

 

Thanks!

Sure! I have sent you the file at support@exlevel.com

 

Thanks a lot for your file!

 

You've very incorrect wind settings. Stiffness is very small, although it should be within the length of the branch or more. As a result, you had to set the value of the Scale frequency is also very small.

Although on the other hand you got the desired result :)

 

And thanks to your settings, I found the cause of the problem and fixed it now. With the usual settings it doesn't manifest itself.

 

What is the problem: Since we fixed some problems, I described it here:

Also, it concerns the Perturb Speed and Perturb Vector in the Wind helper settings. For example, if you created grass on a certain surface and want to generate wind, then the wave that occurs when using Perturb Speed or Perturb Vector will move in the same direction where the wind is directed. In previous versions, the direction corresponded only if the orientation of the surface object was aligned along the global coordinate system. Although this improvement could be called a fix.

 

 

So when you moved your plant some distance from the scene center, this new problem appeared, because your perturbation speed more than the speed of the wind.
Now I've removed the influence of the plant position on all perturbations, and the problem has been solved.
At the moment you can simply move your plant to the coordinate [0, 0].
Also later today you can download the new version when we update it on the server. I'll let you know.

 

Thanks again!

Thank you so much! I moved it to the zero coordinates for now and it's working well. Sorry about the wind settings. I usually focus on the movement of branches. I will read the documentation on Wind Animation again to understand more about its parameters. 

 

Thank you!

Wind settings is simple.

 

Here is wind speed table

beaufort-wind-scale.gif.8851be31eb3d380c6462b084ec884b9a.gif


Set wind speed from 1 mps (almost calm) to 5-10 mps - good wind

 

Set stiffness for branch equal to branch length. Fore example if branch length = 1 meter, then stiffness = 1 meter.

 

Set desired flexibility & frequency.

 

Tweak turbulence :)

This is awesome!! Thanks both of you. @mentor and @Eduard . I'll download the new version.
