# PRIM_PHYSICS_SHAPE_NONE

*LSL constant*

```lsl
integer PRIM_PHYSICS_SHAPE_NONE = 1;
```

Physics shape type setting. Directs the physics engine to ignore this prim entirely, preventing it from contributing to the linkset's physics shape. Note: Cannot be applied to the root prim.

Constant groups: [PhysicsShapeType](/constants/groups/PhysicsShapeType/)

Used with [PRIM_PHYSICS_SHAPE_TYPE](/constants/PRIM_PHYSICS_SHAPE_TYPE/). Prims of this type are ignored by the physics engine. Read more details on [PRIM_PHYSICS_SHAPE_TYPE](/constants/PRIM_PHYSICS_SHAPE_TYPE/)
