Hello everybody,

I have a tree with a simple round shape as crown. From that I emitted particles and instanced them with a cube. To the cube I assigned a proxy leaf.
So far so good- there is a tree with leafs after rendering with mental ray.
Then i put the tree, the particle system and the cube in one group and saved the maya ascii file as finaltree.ma.
Now I have a new scene with a large plane and on the there should be a forrest.
I imported the finaltree .ma
as referrence into the new scene.
From the plane I emitted particles and instanced them with the tree.
But after rendering in mental ray- only my referenced tree (the imported one) has leafs and the instanced particles do not have leafs.

I do not know how i can solve the problem. Maybe it is the wrong way at all.

Thank you in advance.
