1. Summary and Description: There are some issues with custom sounds; a) custom sounds can be heard from any distance, at max volume, and even if obscured by a planet. b) custom sounds stutter or clip when camera movement is taking place. 2. Code used (this is javascript, and based on mikeyh's custom sound mod): try { function audioSounds() { var files = [ 'EMG_weapon_fire.wav', 'EMG_weapon_hit.wav' ]; //cues to be replaced, make sure files and this are 1:1 var cuesToReplace = [ '/SE/Weapons/veh/tank_light_fire', '/SE/Impacts/shell_tank' ]; var fileLocation = '/pa/soundfx/' for(var fileIndex in files){ api.audio.registerCueMod(cuesToReplace[fileIndex], fileLocation + files[fileIndex]); } } _.defer(audioSounds); // hack relies on synchronous code to defer register until after reset } catch (e) { console.error(e); } 3. Steps to reproduce: Use code as above, but rename custom variables (i.e. EMG_weapon_fire.wav) to your choice, any custom sound will work. Then just proceed to a sandbox game and place and attack with the unit which uses said custom sounds (in this case any vehicle that uses the sound 'tank_light_fire', such as the Ant). 4.
