Uneven Branch Distribution


Recommended Posts



I've recently started learning GrowFX in past week, and It's amazing plugin with so much potencial.

At the moment I'm still running on a demo (since I have to save up a little more  money for educational licence :D ).


I came to the point, where I'm struggling with a difficult problem - creating uneven branches on second level.


Since level feature doesn't look very user friendly to me, Im creating my branch levels with 2 paths, then generating twigs, and then scattering it with instanced geometry of needles.


Problem is, that even though I'm trying to use random count, with value 2, its more likely that all my branches dissappear instead of randomisation between 2 and 1 in count. Or else - I only get 2 all the time and sometimes on, but very rare.


This is an illustration of what I'm trying to get - oywx7KE.jpg


Is there any simple way to achieve it?



By the way- here is where I'm so far :)




Thanks for any help or advice!

Hello nabelekm,


For your Branch level 2 in the Path distributor settings, please set the Turn axis = 180. 

Also you can set the Start vector: Angle axis = 90, to turn all the branches along the level 1.

And add an Affect from the Parameter: Path position to the Length of branches ...


see my screenshots:







BTW, your fir tree looks cool :)

Thank you!


Well, there was a little misunderstanding - I'm using affects already, with no problem...


my problem is, that all the time im trying to create branch level 2, my secondary branches look like this



Finally, I've figured out the distribution of the branches from your screenshot... But now I cannot control the vertical angle of the secondary branches with the Angle Bend, because its controlling the horizintal angle. I've tried using hard bend or vector direction, but I think its more complicated way. 


Is there any way to achieve the distribution (like I ilustrated in my first post) with Angular distributor?

Hello, thanks for a fast reply.


That method works, but I lack the ability to control the angle between the secondary branches - they are distributed properly, but flat. and I'm not able to control it with any parameter (only vector direction modifier, but that is still not what I want)


Underneath is my approach, but as you can see, the distribution is wrong, but I'm able to control the angle using Angle Bend
