So I've got a problem popping up. I was following this video tutorial https://www.youtube.com/watch?v=iPOSAJuoEmU&index=3&list=PLvFQDY1Hrbb41mId9Evuvz3pDrHaGFDYI
I have noticed however that many of my trees are floating above the planes they are supposed to be growing from, which causes the immediate problem of shadows only appearing under some trees. I've checked around online, but most Q&A's similar to this one are because the person didn't use "Hair" or had their trees at the wrong orientation. I have tried to do what these other answers I have suggested but without much luck.
I don't mind if the distant trees float, but the ones on the closest mountain face are very obvious in the render. So any help would be great! If I have to I will just go through and manually move them if there is a way to do that! I just need them firmly in the ground, so to speak haha.
