I’ve been looking for quite some time and could not find a proper answer to my problem. I’m trying to add custom leaves and fruits to trees created with the Sapling add-on. For that, I chose square leaves, and split in half the base segment of each leaf, so that I could select the set of all vertices located at the base of each leaf on the branch - let’s call that objet “petioles”, for lack of a better idea.
For the record, that process is very clearly explained in this thread (matali’s answer).
Now that I have that set, I can add a particle system to it and attach a “fruit” objet at the base of some leaves, which is nice. Now I want each fruit to have a natural fruit position : downwards, away from the trunk in the vertical plane of the branch (they are not cylindrically symetric, think bananas or figs).
My concern is that each vertex in the “petioles” object has a vertex normal that points towards the origin of the tree, and there is no way I can use that to have a proper fruit position, even when tweaking rotations in the particle system. I tried to add a “normal edit” modifier, but it seems only to apply to “vertex-per-face” normals and not to mere vertex normals as I have (see screenshot below for illustration).
I would just like to edit those normals, so that they point basically downwards and somewhat apart from the trunk. Is that possible? Or is there a better idea to position my fruits and custom leaves?
