> Quote - I suggest you load a single plant as an object to your scene and open it in the plant editor. The fifth button to the left is a button that defines the "respond to wind" property. Use different numbers in the two input fields and then save your plant out as a new *.veg species (not as a *.vob file!). Repeat this process and enter different numbers each time and save them out as new *.veg species. Five or six different *.veg species should do it. Then repopulate your ecosystem with your newly created *.veg plants. This way you still have the same tree or grass five or six times in your ecosystem, but each one has different wind reactions. And you don't have to mess with a per-plant wind, you can keep your ecosystem :-)

OK!
I followed your suggestions.
For the Breeze I got decent result.
But I have another Color problem!

I created three custom "YellowMapleTree" plants with the same yellow color for leaves and with the same color for "OverallColor" property in the PlantEditor (this because I have 3 plants species with 3 different responses to the wind).
But when I rendering them, a few of them, appear as red colored, not yellow colored, and a few of them appear correctly yellow colored as in the attached image.

-Why?

• How can I do to make them yellow colored as they are in the PlantEditor in the time of creation process?
• How can I do to discard this red randomness of the yellow plants color?

Thanks!
