View source for BSP (Source)/Static prop flags

These flags are defined in {{file|public/gamebspfile|h}}. Any undefined flags are unused by the engine and can be used by custom VRAD compilers to define additional light baking parameters (in conjunction with a modified VBSP that can write those flags).
== Flags ==
This is 8-bit (unsigned char) in all versions of the static prop lump except for {{src13mp}}, where it is 32-bit (signed int).

| STATIC_PROP_FLAG_FADES
| none
| Set by engine at runtime if the model fades out at a distance.
|-

| STATIC_PROP_USE_LIGHTING_ORIGIN
| none
| Set by engine at runtime if the model's lighting origin is different from its position in the world.

| STATIC_PROP_NO_DRAW<br>{{since|{{src07}}}}<br>{{removed|{{portal2}}}}
| computed at run time based on dx level
| Set by engine at runtime based upon {{code|mindxlevel}} and {{code|maxdxlevel}}. Does not work if set explicitly; set maxdxlevel to a low non-zero value such as 50 instead.

| STATIC_PROP_NO_PER_VERTEX_LIGHTING<br>{{since|{{src06}}}}
| in vrad, compute lighting at lighting origin, not for each vertex
| Set if {{code|disablevertexlighting}} is enabled.<br>Contrary to the dev comment, this disables pre-baked lighting for the model altogether, making it lit the same way as {{ent|CBaseAnimating}} props (ex: {{ent|prop_dynamic}}).
|- 
| align=right | 0x80
| STATIC_PROP_NO_SELF_SHADOWING<br>{{since|{{src06}}}}
| disable self shadowing in vrad
| Set if {{code|disableselfshadowing}} is enabled.
|- 
| align=right | 0x100
| STATIC_PROP_NO_PER_TEXEL_LIGHTING<br>{{only|{{src13mp}}}}
| whether we should do per-texel lightmaps in vrad.
| Set if {{code|generatelightmaps}} is ''disabled''.<br>If [[VRAD]] is fed an older version of the static prop lump with 8-bit flags, this flag is treated as always being enabled (not generating lightmaps for any props).<br>This flag is ''only'' read by VRAD; the engine will load the the [[PPL]] file associated with a given prop regardless of this flag, provided STATIC_PROP_NO_PER_VERTEX_LIGHTING is disabled and the checksum in the PPL file matches the checksum found in specified MDL.

== FlagsEX ==
{{csgo|2}}'s static prop lump adds an extra 32-bit (signed int) set of flags, most of which are unused.
