Issue using Impostors with Landscape foliage > random Yaw set to true

Hello!

I cant seem to get instanced foliage (with lowest LOD using an Impostor) to work with rotation on landscape.
Placing as an actor or not using random yaw in the landscape tool seems to work fine.
You can see they all match except for the rotated foliage.
Im sure this has something to do with accessing the instance Yaw as an offset, but I am not sure where to look.

any help is appreciated.

I am using this:
Impostor Baker

But I have already fixed these issues:
error in shader
rotation issue

if I go into the foliage placement tool in Landscapes, I can select and rotate the instance and see the lighting change but the Uv index in the texture sheet does not reflect the rotation.
