You can select the flat ground texture and then adjust it's color in advanced so that it's 100% invisible, but this is just an easier way of doing it.
doesn't this already exist? or at least i remember seeing it in the preview.
I'd rather not download it..
If you want see the below, How you going see it? please explain to me.
Set the ground color to transparent.
I confused by those images. Which one is default and which one uses this texture? Obviously the one on the left is better one.
