Don't include the lazy precompiled.h everywhere, only what's required for the compilation unit. platform.h needs to be included instead to provide all essential defines and types. All includes use the relative path to the neo or the game specific root. Move all idlib related includes from idlib/Lib.h to precompiled.h. precompiled.h still exists for the MFC stuff in tools/. Add some missing header guards.

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.
