How do you prevent Foliage leaves from being too far apart on your model?

1. Here's how

(showing Lumion 12)

There is an upper limit to the number of Foliage leaves per polygon for a model. On a large polygon without any sub-divisions you won't see as high a leaf distribution.

1.1: If the model contains large polygons, simply sub-divide the polygons that lack Foliage density and re-import the model in Lumion:

Before sub-dividing the large polygon, the Foliage leaves are far apart:

After sub-dividing the large polygon in SketchUp, the Foliage leaves are distributed more densely:

Note: adding lots of Foliage can have an impact on screen redraws (FPS) and render times. Please use sparingly.
