I am trying to integrate a simple tree (from blender tree-generator) as a particle system on a plain. But everytime i do that, the tree is pasted seperately, so there are flying leaves next to the main tree. Do you have any idea where my fault is?
Are they two separate objects in a group and you’re instancing the group? If so, check the “whole group” box in the particles panel. That will copy the entire group onto each particle instead of picking a single object.
