====== Forest Block objects ======

As many of you know, OFP use 50meter x 50meter forest block objects, these filled up whole WRP Cell therefore you didn't had to place 20-30 tree objects there, just 1 forest block object. With this system we were able to create insanely thick jungle bush etc.

Then game along ArmA... and something was changed in the engine, so now all the 50m forest block objects float in the air or having that "flying trees" effect. It was bad, if your mod was using a lot of these forest blocks you were doomed as the flotation was utterly bad.

The solution is to use geometry **placement** value of //slopeLandContact// in your p3d model, like this:

LandContact LOD

Geometry "placement = slopeLandContact"

It works nicely as you can see below:

Its tested on pretty rough terrain as you can see, I cannot get it to float, no matter how I place them. 

====== Notes ======

I would like to shout out my heartfelt thanks for Q and The-F for solving this problem.

There is serious issue with this method which was only discovered later after this wiki page was created. When using this method, it causes extreme CPU slowdown meaning FPS loss. This was tested on the thick jungle 12km x 12km terrains. We have no explanation why it happens, but basically it makes any 12km terrain unplayable.
