If you look in the top left there are a ton of Parts, but I don’t want to delete any of them. Its so laggy it sometimes crashes when I try to play it. I have no idea what to do. You can try to join it here but u might crash in Roblox The woods - Roblox EDIT the game is now unable to be played for now.
Wow, 10k? That’s quite a lot, you should go with what Luka said instead, because unions are only for low amounts of items. I thought you only had something 1000 trees.
If it still lags consider changing up your lighting settings, If you have DOF (Depth of Field) or you are going to use it in the future… I don’t recommend to as It also could cause lots of lag.
