How to attach a model to a creature using an effect.

remembered that I updated the mod for the arrows (because it's more convenient for me to work with).

Initially, the plan was to insert the xyz model into the modelinstance before inserting the actual model, but I almost never do that! I always specify in the effect xyz.(ModelInstance) to insert the bone and simultaneously see the direction of the bones and the model I'm attaching.

Now, only xyz needs to be specified in the effect to add the modelinstance (and insert the desired bone into it).
