Is there a guide or something to make this work? I used the Glass one a base. 1. i copied the part from PhsyicalMaterials.sbc 2. i copied the part from MaterialProperties.sbc (link to walk, run etc.) (with "Character" header) 3. i copied the part from Audio_player.sbc (link to the wav files) 4. i bind the Physical Material to my block with the <PhysicalMaterial>MatName</PhysicalMaterial> Tag For testing i replaced all wavs in my Audio_player code part with a wav from SE itself that wasn't made for footsteeps, so i hear directly if it work and put it in my mods folder. I also copied both, all for male and female character and also for Arcade and Real Sound. SE itself shows 0 errors on loading on the Debug Screen and also nothing in the logfile. But the sound is never player, when i walking over my block, still the normal metal footsteps sound. Is there any wrong or a missing step? --- Automerge --- Ok, it is a Bug of the game. I have opened a Bug Report: https://support.keenswh.com/spaceengineers/general/topic/footsteps-audio-bug That Bug make it impossible to add different Footstep sounds on a block like a Carpet.
