Character 3D icon on top of the screen as UI


The following is a UI image element. I searched all over YouTube and i was unable to find tutorial about how to do the following. I want to put 3D character model in this frame, but it should be visible only in the circle. If the model is too large in size, i don’t want the rest of the parts of his body to be visible outside the circular UI.

This is what i want to achieve.

Thanks for the attention.

Hello… any help here?
