Volumetric Translucent Shadow for foliage?

Hello.

If I place single StaticMesh with Volumetric Translucent Shadow - it’s works fine:

But I can’t find Volumetric Translucent Shadow in Foliage settings:

As result - foliage doesn’t cast shadows:

How to enable Volumetric Translucent Shadow for foliage?

Thank you!

Solved!
I have changed material of the tree from Translucent to Masked and switched off Volumetric Translucent Shadow and now all works fine!
