So summon armorstand with commandblock with this command
/summon ArmorStand ~ ~1 ~ {CustomName:,Equipment:[{id:,Count:1},{id:,Count:1},{id:,Count:1},{id:,Count:1},{id:"skull",Count:1b,Damage:3b,tag:{SkullOwner:""}}],Rotation:[-858993460f],Pose:{Body:[-858993460f,-858993460f,-858993460f],Head:[-858993460f,-858993460f,-858993460f],LeftLeg:[-858993460f,-858993460f,-858993460f],RightLeg:[-858993460f,-858993460f,-858993460f],LeftArm:[-858993460f,-858993460f,-858993460f],RightArm:[-858993460f,-858993460f,-858993460f]}}
and now place some entities down and see whats happening, if it doesn't work break armorstand and try again. Note: My hand is upside down because my skin, not because armorstand 😃
And im running completly vanilla minecraft with no resourcepack.
