Sorry to say, though disappointed in the new version.
The engine has no improvements.
Thanks for the new assets though we should concentrate on improving the engine rather than worrying about the assets.
The ability to add materials easily.
I have many materials I have made with substance designer which I would like to share, though too much effort required to create.
I like the grass though very time consuming adding one at a time. To duplicate you need to go to menu and edit, be nice if we could duplicate with a click of the mouse.
Also, a scatter would be good or instance the grass around the ground plane.
The existing sliders should have an up and down arrow at the end to adjust because difficult to make fine adjustments.
