I'm finally getting closer to what I need for a good crucifixion scene. It's a shame that compliance with my prompt is so random. I used this prompt:

Pam, a naked woman tied down at her wrists and ankles to a wooden cross on the ground. PAM CANNOT MOVE HER HANDS. PAM CANNOT MOVE HER FEET. She can only squirm helplessly.

A solitary young, pretty black-robed nun enters the scene from above, carrying a mallet in one hand and sharp railroad spike in her other hand. Pam opens her eyes wide and looks terrified.

Zoom in on the palm of the Pam's hand, keeping Pam's face in view.

The nun places the tip of her spike in the palm of the Pam's hand, and hammers the spike through the permeable palm and into the wood of the cross. Blood spurts from the wound.

Pam screams.

DO NOT EVER LET PAM'S HANDS OR FEET EVER MOVE FROM THEIR ORIGINAL POSITIONS.

...and on the forth try I got this. The previous clips had freaky stuff like the woman turning into two women, more nuns than I'd asked for, etc.

As you might guess from this prompt, it's hard to convince the rendering model that the subject can't move her hands anywhere she wants. At some level the model seems to understand that a human being would try to resist what's happening.
