Just trying to have everyone's grave to be their own head on my self hosted server. so far I got the skeleton_head changed to player_head but it's steve's and not the specific dead person. Do i need to set up a custom model for everyone on the server? or is there a simpler way?

"model": { "default": "player_head", "alternative": [], "hide_f3_debug_lines": true, "gravestone_item_base": "minecraft:player_head{display:{Name:"{\"text\":\"${player}\"}"},SkullOwner:"${player}"}" },

There we go. this dose it.

I have been able to get it to show my head via
"model": { "default": "player_head", "alternative": [], "hide_f3_debug_lines": true, "gravestone_item_base": "minecraft:player_head{display:{Name:"{\"text\":\"Markes12344\"}"},SkullOwner:"Markes12344"}" }

via the config.json edit.
tho I feel i'm right beside the right track.
This shows my head no matter who dies. still trying to figure out how i can get everyone to have their own head shown on their own grave
