Strumpy Shader and Billboard tree

Unity Engine
1

I´ve made a shader with Strumpy that has problems when UnityTerrain-Trees start billboarding:
The trees dissapear behind my shaders object, so there´s a Rendertype / Renderqueue issue.

What is the setup I have to use in Strumpy?
The shader needs transparency(, it fades out at the surface boarder).

Offset the Queue to be something like -100 and keep it in Transparent Queue.

Better, but still not working correct, trees still dissappear…
