    Ultimately I want this scene as something that would happen after the woman has been nailed to the cross, the ropes cut away, and she been raised up to hang from the nails.

    But, as hard as it was to get this reasonably close to right, I'm pretty sure a good take on hammering big spikes through hands and feet is going to take even more work.

    The tough part was convincing Wan 2.2 to make the sword go through those massive breasts. No matter what wording I tried the model had a hard time at deciding to do anything more than have the spear tip poke into her nipples or slash its way over the skin on top... when it wasn't otherwise doing completely bizarre shit way off from what my prompt asked for.


    I tried to use "Time to Motion", but that didn't help.

    The big breakthrough was finding a Wan 2.2 workflow that let me provide both a start and an end image. That meant I had to use some I2I and Photoshop to create an end frame image, but at least once I had that I finally made the tit skewering action something the model could grasp.

    This was the prompt that finally got the job done:

    Character: 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.

    Character: Man, holding a spear aimed at Pam's breasts. He is eager to impale her breasts.

    Action: The man immediately drives his spear violently through Pam's soft, permeable breasts which offer only a little resistance to the spear. The spear passes through Pam's breasts the way a kebab skewer impales pieces of meat. Pam's breasts are jostled as the spear passes through them.

    Pam screams in agony.

    A SMALL AMOUNT of blood TRICKLES from the wounds inflicted by the spear on both sides of the pierced breasts.

    The spear moves in a direct, straight path from start to end, taking about 5 seconds to pass through. Forward speed is slightly uneven as Pam's breasts weakly resist the passage of the spear.

    Sharpen blurred details at the end of the clip.

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

    Here's where you can get the first/last frame workflow: https://weirdwonderfulai.art/comfyui-workflow/first-last-frame-with-wan-2-2-video/

    Thank you so much for the work flow! That helps A LOT! Question too - how long do your renderings take? I'm wondering how I can reduce the quality down so it doesn't take an overly long time (less than 10 minutes?) when I'm just trying to get the prompt correct.

    So far I've identified that the KSamplers (Advanced) are the work horses. I've reduced them down from 20 steps to only 5, and put the 5 as the end step for both as well.
    I've reduced down the output to 640 x 360 and reduced the frame rate to 25 fps.
    So far its running faster, but we'll see how fast. I'll report back on a rendering time approximation.

    Huh. Well, putting down the settings that low blew up on my face pretty hard. I got a blurry dark scene that turns into another blurry dark scene. Hmm.

    Glad to help a fellow perv 😄

    > That helps A LOT! Question too - how long do your renderings take?

    Normally in the 2-20 minute range, depending on resolution. Simple still image things can be just 15-20 seconds.

    Funny timing you should bring this up now. I hadn't used the first/last workflow in a while, but just this moment I'm wondering how damned long my current first/last render is going to take.

    I didn't take note of exactly when I started this particular task, but it's been at least 30-40 minutes, and I'm only 80% through the first of the two KSamplers.

    I did a low-res test of the task first. That only took 2-3 minutes. I upped the resolution to near-HD (1328x992), and, wow. Maybe an hour from now I'll have something.

    I've normally been messing around at 480p or 720p. I upped the resolution today because I was hoping to avoid image degradation when I fed frames from one render back into another.

    Oh, about the idea of reducing the quality until you get the prompt right... it's definitely a good thing to do, but simply changing resolution after you think you've got things right can cause random deviations from the results you got before, even with all the same inputs and seed values.

    This issue was driving me crazy last night when I finally got a good result for an effect at low-res, and then it tooks dozens of retries with and without prompt changes to finally get what I wanted again at higher res.
