hi Frivolous : )
Making trees is simple as everybody can do it, you need Photoshop to edit the image. You will need 5 images for leaves, 1 image of flowers, 1 image of fruit, 1 image of bark pattern. All images are 512 x512 and have a transparent background: PNG file.I often download free images on the internet, make sure they aren't copyrighted, then edit or paint over with Photoshop.

The most important part : the base of leaves must be at the center of the image. And because the flowers will fall off in just 1 hour, I often use the image of the flowers as leaves to ensure that the tree always has flowers.

how do you make a tree? What kind of modding goes into something like this?
