Hey, I have two questions:
- If I create a project in Unity 3D 2.6, could I move it in version 3.0 and continue it?
- How to turn on collisions for the trees, which track the terrain using the “Place trees”?
Sorry for english i form witch Poland 
I recently experienced it with a friend and we had some issue doing this… He is the programmer working with the pro version and got 3.0 and I am the artist working with the free version making the asset ready… But when he imports my 2.6 project in his 3.0, he is getting some issue 
- You can largely do that. There are some minor differences and some changes that require porting but its a one time thing, you won’t do it that often
