# RC_DETECT_PHANTOM

*LSL constant*

```lsl
integer RC_DETECT_PHANTOM = 1;
```

Flag used with llCastRay. If set to TRUE (or non-zero), detects both phantom and volume-detect objects (they cannot be filtered individually). This overrides the RC_REJECT_NONPHYSICAL and RC_REJECT_PHYSICAL settings in RC_REJECT_TYPES.
