[[SPR|Sprites]] have an oft-neglected texture format, called IndexAlpha, which provides 8-bit alpha translucency, resulting in an effect similar to decals. These are useful for simulating hard shadows "cast" from models, and can also be used instead of infodecal to allow custom decals in multiplayer maps, as well as to more reliably place a decal in a specific location. | |||

Infodecal
infodecal can be used to display decals from decals.wad. This is generally the easiest way to place a decal, however it can be finicky where a decal needs to be placed on the grid in comparison to the brush. Additionally, infodecals can sometimes shift around when reloading a map, and may disappear if enough code-generated decals (such as bullet decals) are spawned.

Sprites have an oft-neglected texture format, called IndexAlpha, which provides 8-bit alpha translucency, resulting in an effect similar to decals. These are useful for simulating hard shadows "cast" from models, and can also be used instead of infodecal to allow custom decals in multiplayer maps, as well as to more reliably place a decal in a specific location.
