Zero length lightmap lump will have NULL tr.lightmaps.
OpenGL1 already has this check, because r_vertexLight 1
would crash Team Arena. OpenGL2 does not disable loading lightmaps
when r_vertexLight is 1 though, so it does not have that issue.
UI's PositionRotatedEntityOnTag is different than CGame's and
UI has switched pitch/roll for Gauntlet/BFG axis to get it to
look like /close to/ how it looks in CGame.
Making UI use the same *PositionRotatedEntityOnTag and axis as
CGame fixes the Gauntlet blade being wobbly in controls menu.
In Team Arena's Harvester mode, players corrupt your memory from beyond
the grave. Gib the players to stop the corruption!
CG_PlayerTokens is called for player entities, including corpses.
The entity number is used for the index in cg.skulltrails which only has
MAX_CLIENTS elements. This results in incorrect memory being overwritten
for corpse entities (as the entity number is >= MAX_CLIENTS).
So limit skull trails to valid entities (entity number < MAX_CLIENTS).
If a pk3 search path is passed to FS_FOpenFileReadDir, a non-zero
file handle is returned if file is not found. This causes incorrect
behavior in FS_ReadFileDir (when a pk3 search path is passed in)
which only checks file handle, not length, for seeing if file exists.
I don't know of any issues in ioq3 caused by this.
It doubles the size of the data compared to the default (22050),
so increase the buffer automatically. Likewise, decreasing speed
doesn't need as much (though that doesn't really matter).
If spawn var key or value is "" it caused R_GetEntityToken (available to
cgame, used by opengl2) to stop parsing, whereas game VM would continue.
Changed it to match parsing used for game VM
(see G_GET_ENTITY_TOKEN in code/server/sv_game.c).
The map poq3dm5 has a "wait" key with value "".
When R_GetEntityToken returns qfalse it resets pointer for parsing, by
R_ParseSpawnVars not returning qfalse it could cause an infinite loop.
Also add newlines to printfs.
Vertex lite surfaces being brighter than light maps looks bad,
they're meant to look the same. Especially in ET, which mixes
them fequently. It's noticeable in Q3 too though.
BSP lightmaps (i.e. not external HDR lightmaps) use
R_ColorShiftLightingBytes, now *Floats (used by vertex colors)
has the same behavior.
This may be a problem for HDR lightmaps, as the RGB will always be
scaled to 0.0 to 1.0 range.
I had enabled this for non-HDR before, but now HDR needs it too.
