Named Selections
In Blender they are vertex groups. In the P3D they are named selections. On the Memory LOD those are the points the game touches.
What you need on the Memory LOD
| Selection | Verts | Role |
|---|---|---|
door1 | 1 | Reference / door-body anchor |
door1_action | 1 | Where the player sees “Open” |
door1_axis | 2 | Axis — two points form the hinge line |
lootFloor | n | Floor loot, like vanilla |
lootshelves | n | Shelf loot |
Lights, sounds, and other action points follow the same pattern: one name, one or two vertices, no faces.
Geometry
On the Geometry LOD, named selections are Component01 … Component32 — vertex groups for collision. See Geometry, Mass, Components.
