/*

|
Meager documentation for how the cubemaps are assigned.
|
||
|
|
|
||
|
|
|
||
|
|
While loading the map, it calls:
|
||
|
|
*** Cubemap_SaveBrushSides
|
||
|
|
Builds a list of what cubemaps manually were assigned to what faces
|
||
|
|
in s_EnvCubemapToBrushSides.
|
||
|
|
|
||
|
|
Immediately after loading the map, it calls:
|
||
|
|
*** Cubemap_FixupBrushSidesMaterials
|
||
|
|
Goes through s_EnvCubemapToBrushSides and does Cubemap_CreateTexInfo for each
|
||
|
|
side referenced by an env_cubemap manually.
|
||
|
|
|
||
|
|
Then it calls Cubemap_AttachDefaultCubemapToSpecularSides:
|
||
|
|
*** Cubemap_InitCubemapSideData:
|
||
|
|
Setup s_aCubemapSideData.bHasEnvMapInMaterial and bManuallyPickedByAnEnvCubemap for each side.
|
||
|
|
bHasEnvMapInMaterial is set if the side's material has $envmap.
|
||
|
|
bManuallyPickedByAnEnvCubemap is true if the side was in s_EnvCubemapToBrushSides.
|
||
|
|
|
||
|
|
Then, for each bHasEnvMapInMaterial and !bManuallyPickedByAnEnvCubemap (ie: every specular surface that wasn't
|
||
|
|
referenced by some env_cubemap), it does Cubemap_CreateTexInfo.
