The only way to add fruit to a tree (as part of the editor) would be to do as the others have suggested and include the fruit in the same texture as the leaf, which isn't really all that great unless it's really far away (as the fruit would be flat since Vue's plants are simply alpha plane leaf textures mapped onto alpha planes attached to the branches of the tree) If you are close up and need the fruit to look real you're going to have to take the time and place the fruit manually on the tree. If you want really sophisticated trees you're better off trying X-Frog or a program that actually models plants and trees. Sorry if you were hoping for more out of Vue.
