This time is a simple tutorial about making in Blender 2D vines growing like in AfterEffects, I have search in the web for it but all I have found regarding Blender are the 3D simple curve growing effects but 2D branching flourish vector growing are much more beautiful and ever present in AfterEffects compositing.
During this week (busy with a very interesting course), I had nonetheless some time to play with Blender and try to achieve this 🙂 so I hope this tip will help people who have wondered the same.
The only limitation I currently see with the method is that you could not control the size of the billboard object in a local way, currently if you animate the size of the particles it will animate the size of all the particles, not the new ones as should be, it is a matter of internal code of the current particle system and I hope in the future could be fixed because then there will not be any limits on what could be achieved with this method.
Other ways to perform this effect in theory could be with animated dupliframes instances that act as a mask but dupliframes seems to not be included in 2.5 and in 2.4x are not animatable 😦
Here is the example file
Cheers and hope you like the tip
