> [!abstract] Summary > **Scene Import LOP** — brings data from the **OBJ context** (the classic Houdini scene) into the LOP / USD stage. Can import everything in one go, or filter by type (geometry, camera, light, null). Auto-picks the right schema for each node. --- # Scene Import - Imports **anything from the OBJ context** into Solaris. - Works for the full scene **or** specific components — **camera**, **light**, **geo**, **null**. - **Automatic picking** — the node maps each OBJ node to the right USD schema (a Houdini light becomes a `UsdLuxLight`, a camera becomes a `UsdGeomCamera`, etc.). ![[file-20241023232607086.png|475]] --- # Typical Uses - **Migrating** an old OBJ-context scene to USD without rebuilding from scratch. - **Mixed pipeline** — keep a legacy OBJ-context FX sim and import its result into Solaris. - **Camera transfer** — pull a Mantra-era camera into a new Karma stage. > [!tip] Prefer Solaris-native nodes for new work > Scene Import is a bridge, not a daily driver. Start new scenes directly in LOPs to avoid the OBJ-context legacy. --- # 🔗 Related - [[../SOLARIS MOC|SOLARIS MOC]]. - [[SOLARIS Reference VS Sublayer VS Merge|Reference VS Sublayer VS Merge]] — for USD-native imports. - [[../HOUDINI Lop Import|LOP Import]] — different node, imports from another LOP graph.
