# Grass Batches

Grass batches are represented as a mesh with only vertices, where each vertex represents a grass instance. Attributes are used to store per-grass instance settings.

Geometry nodes are used to generate and preview grass batches. Each grass batch is configured through a list of "templates", which define the models that can appear and their per-model settings (e.g. scale, LOD distance). The geometry nodes modifier then uses these templates to scatter the grass instances over a base mesh.

The geometry nodes require Blender 5.0 or newer. Import/export still works on all supported versions, since the grass batch itself is just a regular mesh containing only vertices. This also means some manual editing is possible.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.sollumz.org/documentation/maps/grass-batches.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
