I'm Exactly into this nowadays, tips : use bbox("../geo", D_YSIZE) and other bbox values in the plane and uvs to make it more procedural. (would have made the tutorial longer) Also : double the size of the exported textures just for opacity makes the output look more precise (would be cool to add this to the baker node). Make a copytransf of the plane, 180° Y axis rot and you get your asset not disappearing at 180° angle (which double the textures number). Now problem comes from the lightning where you get your plane's shadow covering parts of the other plane > unrealistic, so you have to scatter various planes around the tree taking into account the branches placements, merge the uvs, then same process. You'll have to modify a bit your textures into cops or photoshop to make them match the render look of the other LODs. this is so cool there is a tree generator inside Houdini ;) ++
Pretty straightforward. For this create a new grid put some uvs on it and put down a quick material node set the colour to your baked texture. Take this and plug it into the third input of the tree leaf generator. If your leaves dissappear at certain angles you can go one step further by turning your grid into a cross billboard. Take your grid and transform it 90 degrees and merge with the original. While this doubles the amount of polys per leaf it also fills out the leaf canopy and looks better for glancing angles.

Hi, a question in that quick material node is there a displacement texture?
excuse my ignorance but how do load in the baked textures to use as our leafs ?
