  1. What is REVERBD?

REVERBD is a Enviromental Reverb script that assign Reverbs on individual Map sectors.

  1. How to use it?

REVERBD can be loaded as a lump inside a .wad file.

REVERBD is also independant from the map related lumps, which allowing it to be added

even if the map is already made.

  1. REVERBD structure

In order to apply reverb on two sectors in the same room REVERBD should be like this:

map E1M1: Hangar

reverb "0" {
	"environment" 26
	"environment size" 5.0670
	"environment diffusion" 0.8360
	"room" -411
	"room hf" -685
	"room lf" 0
	"decay time" 3.3710
	"decay hf ratio" 0.6990
	"decay lf ratio" 1.0000
	"reflections" -55
	"reflections delay" 0.0750
	"reflections pan" 0.0000 0.0000 0.0000
	"reverb" 27
	"reverb delay" 0.1000
	"reverb pan" 0.0000 0.0000 0.0000
	"echo time" 0.0850
	"echo depth" 0.0000
	"modulation time" 0.2500
	"modulation depth" 0.0000
	"air absorption hf" -5.0000
	"hf reference" 5000.0000
	"lf reference" 250.0000
	"room rolloff factor" 0.0000
	"flags" 63
}

reverb "1" {
	"sector" 0
}
  1. REVERBD parameters

REVERBD is heavily based on Doom 3's .efx files.

Unlike Doom 3's .efx files REVERBD comes with two different parameters.

map Mapname shown on automap : This is used to define for which map the following reverbs will be loaded for

"sector" #of sector : This is used for getting the reverb of a sector that has already reverb (so sector 1 can't get the reverb of sector 2)

Also on REVERBD the reverb "number" is for setting which sector should use that reverb the number is the sector index number (so far Slade map editor can show them)

The Enviroment parameter is ignored

For the rest of them, they are indetical to Doom 3.
