tree settings

Hello!

I have a tree which is created by unity tree builder. I`d like to create more trees as copy of this tree, but with some differences. When I copy this tree and add some changes - this changes are applied to all copies at once.

How can I add changes not to all?

This is my technique on creating different trees. Here are my steps.
Step 1: Open your Assets folder and open your tree builder. If you haven’t moved your tree builder do this pattern.

Assets> Standard Assets> Tree Creator> Trees

Step 2: Rename the tree prefab some numbers on the name of the tree. Example:

BigTree1.prefab

BigTree2.prefab

Bigtree3.prefab

So on and so on.

Step 3: Go to unity and you can now edit it. Example:

BigTree1.prefab has 213 leaves

BigTree2.prefab has 196 leaves.
So on and so on.
