A pest??trees?????Why not LOVE trees instead of hating them!
give them a big wooden hug!
And no,there is no way to filter them out of the Natural/static models!
atleast,not that i know!
Sure would be nice if you could use the group function with brushes to group certain objects ei "filter groups" (for filtering only), then use the filter to hide these certain groups rather than all of a certain category. I am surprised the gamemakers didn't employ something like this themselves.
