I suspect that you did not have your G3 selected when you added the hat to the scene so it is not parented to the head of your model.
I have this Wilpmap set & it follows poses as long as the hat is parented to the figure - The easiest way to fix it now is to delete the hat - Select G3 and load it again and it should work with any poses

Is this in Daz studio? How have you parrented the prop aka the hat to the figure's head?
Yes Daz Studio.
I did as i did with the clothes.
I pick the head - rightclick and drag the UV - fit to genesis 3 female
Then material rightclick and drag - fit to g3f sunhat UV
I am getting confused. Can you show a screenshot of your Daz studio set up?
Here comes a screenshot

I will give it a try again. Thank you.
