Grass

[bigfoot]

It's quite simple, I use it all the time.

Click on the grass in the editor, then set it's properties from collision to false (by unchecking the box).

There! It's done! Except... You'll have to do it with every single grass you placed unless you remove all of it and copy and paste it all on from the original one that has no collision. :/

already removed like 400 of them haha, so I can start over like you said. except at the edges the collision is fine
