More control over smooth terrain grass decoration

[DanBuildsTrains (Dan)]

as a dev, it would be very useful to be able to manually control properties of “decoration” in the grass terrain such as:

• grass height (useful for games that use a smaller scale for battling long maps, such as a train game)
• grass density (useful for various grass styles, but not a big concern. Would be nice to adjust though.)
• grass color offset (big color difference between when decoration is on vs off. See images below)

it would also be useful to apply different grass colors with a “paint brush” application method, such as modeling dry/dead or fresh/lush grass on the same map using 3D grass. Currently, we are limited to whatever the global grass properties are. So the entire map uses the same grass color.

Adding to this, I would like a way to enable so when there is a part on top of the grass, no grass is rendered in that zone covered by the part. Useful for games with a building system where players place anything on the terrain, there will not be any need to replace material and revert back which can be problematic depending on the game.

Currently the grass just goes through anything and there is no way to cause the effect I want except for removing the grass material on such places.
