Hi ulillillia,
I wrote good script for lots of entities. It will reduce entity count and will increase frame rate.
Before in my level i have placed a lot of similar entities like trees /3600trees/.
Now i am creating only 100 trees. These trees are DYNAMIC trees. In my script maximum 100 trees will be visible. if one tree is going invisible to camera, i will place it to another tree location.
Perhaps, my idea will help a lot of people from placing so many trees.
