Prelight models
|
|
|
|
"_prelight_<lightname>", ie "_prelight_light1"
|
|
|
|
Static surfaces available to dmap will be processed to optimized
|
|
shadow and lit surface geometry
|
|
|
|
Entity models are never prelighted.
|
|
|
|
Light entity can have a "noPrelight 1" key set to avoid the preprocessing
|
|
and carving of the world. A light that will move should usually have this
|
|
set.
|
|
|
|
Prelight models will usually have multiple surfaces
|
|
|
|
Shadow volume surfaces will have the material "_shadowVolume"
|
|
|
|
The exact same vertexes as the ambient surfaces will be used for the
|
|
non-shadow surfaces, so there is opportunity to share
|
|
|
|
|
|
Reference their parent surfaces?
|
|
Reference their parent area?
|
|
|
|
|
|
If we don't track parts that are in different areas, there will be huge
|
|
losses when an areaportal closed door has a light poking slightly
|
|
through it.
|
|
|
|
There is potential benefit to splitting even the shadow volumes
|
|
at area boundaries, but it would involve the possibility of an
|
|
extra plane of shadow drawing at the area boundary.

|
|
|
|
Shadow volume surface
|
|
|
|
Surfaces in the world cannot have "no self shadow" properties, because all
|
|
the surfaces are considered together for the optimized shadow volume. If
|
|
you want no self shadow on a static surface, you must still make it into an
|
|
entity so it isn't considered in the prelight.
