To replace the leaves on plants you need a color picture of a new leaf and an alpha picture of the shape of the same leaf to make everything outside the shape transparent. I downloaded the leaves I'm showing here from Varian's website. Let's now replace the plum leaves with crimson leaves. Grow a plum tree and double-click it to enter the plant editor.

1. Click at the leaf button to enter the leaf editor

2. Look where the hooking point is placed in the original leaf

3. Click the Load Color picture button and browse to the color picture of the leaf

4. Click the Load Alpha picture button to load the corresponding alpha picture (in this case it's "tCrimson.gif)

5. To put the hooking point in the right place just left-click at about the same position as it was in the original leaf

6. Click OK and your tree has new leaves. :)

For those who don't have a Vue version with the Plant Editor let's see how to change the leaves in the Material Editor instead. Grow a plum tree and in the material preview click the arrows to go to the leaf material. Double-click it to enter the Material Editor. To make it easy we'll use the Basic Material Editor.

1. Load the color map of your new leaf

2. Load the Alpha map of your new leaf

Click OK and your plum tree has new leaves. I hope that's easy to understand and easy to follow.
