Hello, last few days I was busy with making animated trees and grass for my personal project. I wanted to make trees with wind animation and scatter them with ForestPack, but I've faced with multiple issues. Finally, I've found the way how to make correct cache and use it without any problems. 1) Create tree and add Wind modifier into the After Mesh Modifiers. If you'll add Wind into Direction it will change topology and it will be unacceptable for the Point Cache modifier. 2) Turn on "Convert to mesh" option in the Properties of the GrowFX object 3) Set GrowFX Cache option to One file (For some reason File per frame generates broken animation). 4) Start caching. 5) Test results to be sure that everything is OK. 6) Add Point Cache modifier to the GrowFX object. 7) Set Point Cache record option as One file per frame (this time, for some reason, Point Cache didn't work with One file). 8) Copy your GrowFX object and convert it to mesh. 9) Add Point Cache modifier to the mesh object, and load cache. Done! Now you can scatter your tree model with an animation.
