Painting Trees Grass - Issues: Leaves Grass not showing up...

So I have had a look around the forums and I cannot find the answer I am looking for. Some posts talk about adjusting tree distance and other such options, but it's not really what I'm looking for.

I have downloaded the free terrain assets from the asset store and I am attempting to paint onto the terrain. I am able to paint trees and rocks, however, the trees do not have any leaves visible and even with create tree colliders checked, I can still walk right through them.

My other issue is that I cannot paint any grass what-so-ever, and I have read the other post on this topic and it did not solve the issue. I select different kinds, and paint the ground, but nothing shows up. All the tutorials say it's easy as pie, just choose your grass, pick a brush, and paint away. What's the deal? I have "draw" checked on the terrain options. Are the grass and leaves not showing up linked in some way?

Any help would be greatly appreciated. Thanks.

I managed to get the collider to work for the trees, however, the leaves are still not showing up (I cannot even see the opaque planes when I add leaves to the tree creator - only the blue outlines of what would be the opaque planes) and I cannot paint grass. Any suggestions? Is this just a bug?



In the tree examples in the manual the paintable trees already have leaves. Is it a setting that is wrong? I've been messing with these leaves and grass for so long.

 

I'm having the same problem with the grass in Unity 5.1 . . . HELP PLEASE!!!!

 

Same problem. Collider is on but no grass.
