Dear IPACS team,
I ask again my question here, since not answered yet.
The "hack" with "no__shadow" and "no__collision" works well.
Is there also a "hack" to prevent grass planar surfaces from shining/straight reflecting the sun light? The idea is to get a rather uniformly light grass surface whatever their orientation (diffuse lightning).
The picture below illustrates how light "straight" reflection underlines the planar surfaces.
Orbx obviously have their grass planar surfaces uniformly lighted (diffuse), and not directly reflecting the sun (the aircraft shadow doesn't also interact with their grass). Planar surfaces are too sparse in this example to actually foul the eye, but zones with dense intricate planar surfaces really do the trick.
Thanks in advance
