# Prepare Asset

For your levels to function correctly on Quest, you must prepare your assets, especially when importing them.

## StaticMesh : 

* Nanite must be disabled (not supported).
* Your meshes must have a triangle count below 65,535 to maintain a 16-bit index.
* Your meshes must have LODs if the triangle count is high.
* limited the number of material slots per static mesh to limit the number of draw calls.
* Prefer using simple collisions instead of complex ones.

A tool exists to execute these parameters on a set of static meshes selected in the content browser. **Reality\_StaticMeshTools** : /All/Plugins/Reality/Editor/Tools/Optimisation/Reality\_StaticMeshTools

## Texture :&#x20;

* Prefer a resolution limit of 2048 for textures.
* Switch the compression to ASTC 8x8
* Compress without the alpha layer if it is empty.
* Enable mipmap by default (unless otherwise specified).
* Limit the size of ORM textures if possible.

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:

```
GET https://beyond-sandbox.gitbook.io/realitysdk/documentation/level/optimisation/prepare-asset.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
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.
