Markdown versions of documentation pages are available by appending `.md` to page URLs; this page is available as [Markdown](https://docs.sollumz.org/documentation/maps/occluders.md). # Occluders Occluders are used as a rendering optimization to determine which objects are hidden from view and avoid rendering them. These are stored as box occluders (oriented boxes) or model occluders (low-poly triangle meshes). Occluders are represented as a red semitransparent mesh.

The list of occluders can be found in Occluders tab panel in the sidebar.

Each occluder can be linked to multiple mesh objects which are merged together on export. Each mesh object can use one of the following export modes: * **Automatic**: automatically detects box-shaped mesh islands (upright boxes or planes) and exports them as box occluders; everything else as model occluders. * **Boxes Only**: all mesh islands must be box-shaped. Non-box islands are skipped with a warning. * **Models Only**: export the mesh as-is as model occluders, without attempting box conversion

GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## 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/occluders.md?ask=&goal= ``` `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.
