Tracking player movement for model and animations change

In attempts to get Woodwalkers (parent mod of Remorph) working with GeckoLib (used for entity model and animations) in order to not t-pose around on other players' views, we're going through the PlayerEntityRendererMixin file of Woodwalkers and trying to correct how it tracks player motion into a way that is not so client-sided

Currently it uses this:

shape.walkAnimation).setPos(player.walkAnimation.position());
            //#else
            //$$ shape.animationSpeedOld = player.animationSpeedOld;
            //$$ shape.animationSpeed = player.animationSpeed;
            //$$ shape.animationPosition = player.animationPosition;
            //#endif
            shape.swinging = player.swinging;
            shape.swingTime = player.swingTime;
            shape.oAttackAnim = player.oAttackAnim;
            shape.attackAnim = player.attackAnim;
            shape.yBodyRot = player.yBodyRot;
            shape.yBodyRotO = player.yBodyRotO;
            shape.yHeadRot = player.yHeadRot;
            shape.yHeadRotO = player.yHeadRotO;
            shape.tickCount = player.tickCount;
            shape.swingingArm = player.swingingArm;
            ((LivingEntityAccessor) shape).setSwimAmount(((LivingEntityAccessor) player).getSwimAmount());
            ((LivingEntityAccessor) shape).setSwimAmountO(((LivingEntityAccessor) player).getSwimAmountO());
            shape.setOnGround(CEntity.isOnGround(player));
            shape.setDeltaMovement(player.getDeltaMovement());

Someone from GeckoLib's server has said that it's an issue with Woodwalkers using DeltaMovement, as is the last line, saying that getDeltaMovement is usually set to 0 for the player, and that this is why it's not translating into the new model's movement/animations correctly when in multiplayer

Does anyone know what we would have to change this tracking to in order to make it work?
