Hey guys, I've been using GrowFX for some time now and everytime I need to make ivy on pergolas I'm never quite satisfied with the end result. I feel we need a bit more control on how the ivy spreads over a surface or mesh because it's easy to have the branches bundle together and make a spot too dense and others too sparse.
Also, there's a strange behavior on the Object Reaction modifier. What happens is:
1 - I add the modifier to the main trunk of the ivy and edit the parameters until I'm satisfied.
2 - I also add the modifier to the branches of the Ivy. As soon as I add the modifier, the Trunk moves. This is far from ideal (not sure why this happens) since you loose the look of the trunk. The same happens if you add the same modifier to any other level below - each of them changes the behavior of the last level and moves the splines.
I'm attaching the file with the latest Ivy I managed to make (Max 2016). Notice how the leaves and branches tend to bundle together instead of spreading and keep distance between themselves. Maybe a future update to have better control over this or am I doing something wrong?
