My memory isn't what it used to be, whilst I try to think about the floating problem again, here are a couple of links for you that I found using search.
Maybe you already read them, but just incase you didn't....
One Two3./
les_trojuhelnik_pruchozi.p3d which is not even a triangle
les_trojuhelnik_pruchozi.p3d is indeed a triangle of forest and even looks like a triangle of forest in Oxygen, WrpEdit and the Game Editor.
The Geometry LOD is also triangular.
It is normally used to border the square pieces in order to break up the squareness.
Maybe you meant another forest model.
Here is what BIS used in the CfgWorlds section of the game config for forest replacement.
This is from the class Abel definition:
class ReplaceObjects
{
class ForestBorder
{
replace="data3D\les_su_ctver_mlaz.p3d";
with[]={};
};
class ForestSquare
{
replace="data3D\les_su_ctver.p3d";
with[]={"data3D\les_su_ctver_pruhozi_T1.p3d","data3D\les_su_ctver_pruhozi_T2.p3d"};
center=1;
};
};
I hope some of this has helped.
EDIT: Seems we cross-posted.
