FAQ: Heretic 2's A3D CONSOLE VARIABLES

For A3D console variables for other A3D2 games go to our A3D console variable page.

WARNING!
Changing these settings could seriously affect your listening experience of these games. Only experienced users should change these values; please refer to the defaults listed for each variable to return the game to its original settings.

Brief description of the A3D console variables

Key:

"variable name, in Bold quotes"

• default value
• brief description
• allowable values

"disable_a3d"

• disables A3D

"enable_a3d"

• enable A3D

"snd_restart"

• restarts the entire sound system

"s_buffersize"

• 65536
• size, in bytes, of sound data to buffer ahead.  Currently, each secondary buffer has 65536 bytes of data.

"s_rolloff"

• 0.9
• adjusts the rolloff factor - when the rolloff value is increased, the effects of distance are increased: high frequencies are filtered and volume is lowered.
• 0.0 -> 1.0

"s_doppler"

• 0.00

adjusts doppler

• 0.0 -> 1.0

"s_distance"

• 23
• adjusts the ratio of game units to meters. This affects velocity, positioning, and distance. The higher this number, the closer everything gets to each other (in audio terms)
• 0.0 -> infinity

"s_min_distance"

• 11
• minimum distance before rolloff is applied to a source
• 0.0 -> s_max_distance

"s_max_distance"

• 10000.0
• maximum distance before a source is muted
• s_min_distance -> infinity

"s_2dvolume"

• 0.88
• the maximum volume which 2D sounds are played at. By the nature of the filters being applied to the A3D buffers, they are quieter then their 2D counterparts.  Hence it is important to quiet the 2D sounds to make up for this
• 0.0 -> 1.0

"s_watereq"

• 0.1
• Amount of high frequency rolloff to apply when Corvus goes underwater.  1.0 is air.
  - 0.0 -> 1.0

"s_geometry"

• 1
• Toggles geometry rendering on/off. When disabled, geometry is not processed at all.
  - 0 or 1

"s_occlude"

• 1
• Status of occlusions - 1 enables; 0 disables
• 0 or 1

"s_reflect"

• 1
• Status of reflections - 1 enables; 0 disables
• 0 or 1

"s_refgain"

• 0.38
• Adjusts the gain on each reflection, where higher number means louder reflections. Remember very loud reflections could cancel out the effect of HRTFs
• 0 -> 1

"s_refdelay"

• 1.2
• Delay between a source and its closest reflection.  The higher the delay, the more time it takes between when the source and its first reflection are played
• 0 -> 100

"s_occfactor"

• 0.4
• Transmission value of material - the smaller the number, the more occluded the sound is (less sound passes through the material)
• 0.0 -> 1.0

"s_corvushears"

• 1
• places the listener point where all sounds are positioned in relation to - 1 is on Corvus's head; 0 is on the camera
• 0 or 1

"s_numpolys"

• 400
• Maximum polygons to be rendered. Polygons will stop being rendered either when there are no more polygons left or s_numpolys polygons have been rendered. Setting this to 0 is the same as turning s_geometry off
• 0 -> infinity

"s_bloat"

1.0001

Bloat factor for polygons. This effectively scales each polygon by a certain amount. This is a rough way to fill holes left by unrendered small polygons.
