Same problem here :).
We use Speedtree to create our flora.
The game, we are working on, will be a mobile game, and we can’t get the Speedtree Materials running.
All Speedtree Assets are displayed as they would have no materials in mobile preview.
If we disable the Speedtree Node inside the Materials, which goes into the World Position Offset, then everything is fine, but then we lose our wind on our plants.
And we need Wind in our scene :(.
Any known Workaround for this?
Thanks for your help :).
