It's in worldserver.conf

```text
#
# vmap.enableLOS
# vmap.enableHeight
# Description: VMmap support for line of sight and height calculation.
# Default: 1 - (Enabled, vmap.enableLOS)
# 1 - (Enabled, vmap.enableHeight)
# 0 - (Disabled)

vmap.enableLOS = 1
vmap.enableHeight = 1
```

So this option must be on "1" and you need to have vmaps.
