Can you change Terrain's grass length in a script?

[Athox]

I was attempting to call the terrain grass length by using, workspace.Terrain.GrassLength, but it doesn’t seem to be an option. Any other ways of accomplishing this?

I tried a bunch of ways … nothing worked. Did some research and came across this …

Looks like that option is in beta ATM. So I looked in Beta features and found Grass Length Customization

Checked the option to try the new feature and you can set the grass length from the studio.
However I still couldn’t figure out a way to get to that in a script … So boo, don’t look like for now you can, unless you set it that way in the studio and go with that setting with the beta option set to use with a check. But it looks like after beta you will be able to do that!

You can’t edit grass length at run-time yet, but some sort of solution is planned:

@LightBeamRays

At the moment GrassLength is a non-scriptable property. This is because we don’t intend for GrassLength to stay as a Terrain property in the long term. In the future, we plan to move it to offer you much more flexibility, such as the ability to edit density and have different lengths of grass in different regions of your worlds, among other things. We have more work to do before we can move this property to its final home and offer solutions to those use cases, but we still wanted to get something out to you as early as possible.

More details can be found in the GrassLength section of the Creator documentation.
