+Runtime plugin compatibility
+----------------------------
+
+Before preparing assets, check that the SimWorld executable includes the
+runtime modules they require. A content ``.pak`` extends the assets available
+to the running executable; it does not enable or compile missing native
+runtime modules. Enabling a plugin in your asset-authoring project alone
+does not enable it in the official SimWorld executable.
+
+In the `maintainer response to issue #80 (February 15, 2026)
+<https://github.com/SimWorld-AI/SimWorld/issues/80#issuecomment-3905109317>`_,
+the following support was confirmed for the official build discussed there:

+   * - Physical Animation
+     - Not confirmed in that response; Chaos Cloth support alone does not
+       confirm support for this separate feature
+
+This is a dated confirmation, not an exhaustive plugin manifest for every
+release. For a system not confirmed above, ask the maintainers about the
+specific plugin and SimWorld package version before relying on it. Include
+the required plugin names when requesting support in a future build.
+If a required runtime module is absent, a SimWorld executable built with
+that module is needed; repackaging only the content will not add it.
+
+Once the runtime requirements are met, follow the matching Unreal Engine
+version and packaging steps below. Test the resulting assets in the target
+SimWorld package, including their animation and interaction behavior.
