Sprites--What am I doing wrong

I am using single textured sprites for trees. Looks okay.

Can`t get collisions between player (mesh) and sprite to work.

Does this work, if so how ?

Collisions for other entities is fine.

Don't know about sprites being allowed to collide with other entities (if you know what I mean, since that statement is badly worded), but you could create a pivot at the some position as the sprites and use that for collision detection.

Or try to use at least EntityRadius or EntityBox for the trees to make them something more than 2D.
