I have noticed that the grass has ceased to move, in the new version.
In the previous version all was normal.
I create a grass by means of MeshBase:: createGrass (...).

Hi, this was mentioned in one of the version history release notes, that MTECH_GRASS will currently affect only grass rendered with the Grass class.

Advanced foliage rendering will be implemented later, which will support more kinds of grass/plants.
