SimpleGrassTextured

This plugin for Godot 4 allows you to add grass and plants to your scene in a simple way

How to install

Close all your scenes

Especially those in which there is some SimpleGrassTextured
Disable SimpleGrassTextured in Project -> Project Settings -> Plugins
Delete the folder 'addons/simplegrasstextured' on your project
Install the new SimpleGrassTextured version
Enable SimpleGrassTextured in Project -> Project Settings -> Plugins
Reload Godot

Add a SimpleGrassTextured node to your terrain scene

Your terrain scene must have a StaticBody3D in order to draw grass on top of the terrain

Select the SimpleGrassTextured node on your scene and draw on the terrain

In the _ready function of your game scene you must enable the interactive mode by calling the function SimpleGrass.set_interactive(true)
Next you must enable the character to be detected by the SimpleGrassTexture collision system, for this it is recommended to add a MeshInstance3D to the character (for example a sphere) at the height of the ground

you can adjust the size of the sphere so that the collision be detected more accurately
In the render layers of the MeshInstance 3D, only layer 17 should be enabled
Note: this same procedure can be done for each character or object that must interact with SimpleGrassTextured
In the active camera disable display layer 17 so that objects that are only interactable with SimpleGrassTexture are not visible
In your character's _process or _physics_process function update SimpleGrassTextured by calling SimpleGrass.set_player_position(global_position)

Select the SimpleGrassTextured
Using the inspector load your custom mesh on the mesh propierty
On the Texture Albedo load your custom texture for the mesh

Optionally in the "Material parameters" section adjust the appearance of the material

For short grasses in which it is not necessary to have shadows, they can be turned off via the SimpleGrassTextured menu in the top bar

If you have enabled the interactive mode, can speed up the loading time by baking the heightmap (mainly if there are a large number of grasses), you can do it in the SimpleGrassTextured menu on the top bar

Be sure to do this if you make any changes to the grasses.

Use the "auto center position" tool in the SimpleGrassTextured menu to adjust the node position, this way you make sure Godot's LOD system works correctly
If your custom mesh does not display correctly try adjusting LOD Bias
