Func group is virtual entity used to group brushes and patches together for convenience (selecting, moving, copying, etc). Also func_group can set explicit compiler-related entity keys to it's brushes. Regular entities cannot be grouped with func_group.
Important: When map is compiled, all func_group entities are merged into worldspawn.Entity key list
| Key | Description | Default value |
|---|---|---|
| Luxel scale | _ls | Lightmap pixel (luxel) size is scaled with this value. Lesser = better (luxel size cannot be less than 1 unit). Typical values are: 0.5 (double lightmap reqolution, high quality), 0.25 (quadruple lightmap resolution, very high quality), 2 (half lightmap size, low quality). Note that this is multiplier to default luxel size set by material or map build script. |
| Cast shadow group. | _cs | See shadow groups. |
| Receive shadow group. | _rs | See shadow groups. |
| Vertical texture projection | _vp | Forces a vertical texture projection to be used instead of brush/model/patch base UV coordinates. A value is size of texture in game units. Typical values are: 128, 200, 400 etc. |
| UV Scale | _uvs | Scales U/V coordinates. For fixing badly scaled terrain models. |
| Smooth normals | _np | Sets normal smoothing for entity brushes. See normal smoothing. |
| Patch meta | _pm | Forces curves to be baked as regular models. |
| Non solid | _ns | Disables BSP planes generation for entity brushes. Use on never-reachable surfaces or surfaces that will use BIH collisions (like brush terrain). |
