    This LoRA focuses on generating sequences related to different kinds of expansion and weight gain.

    What's new?

    v1.8:

    • v1.8 has different main trigger words for different sequence lengths:

    • 2 stage sequence: before and after

    • 3 stage sequence: transformation sequence

    • 4 stage sequence: sequential transformation

    • Using multiple views with 3 or 4 stage sequences might help if the model is being stubborn.

    • An example prompt for a 2 stage breast expansion might look something like this:

    before and after, 1girl, small breasts, huge breasts, breast expansion, ...
    • Or like this if you want three stages:

    transformation sequence, 1girl, small breasts, large breasts, huge breasts, breast expansion, ...
    • Recommended resolutions (that I've tested so far):

      • 2 stage sequence: 1024x1024, 1280x1024, 1536x1024, 1368x1024

      • 3 stage sequence: 1368x1024, 1536x1024, 1792x1280

      • 4 stage sequence: 2048x1024

    • If you end up with boring backgrounds even when specifying a location, try adding this to your negative prompt:

    simple background, white background, gray background, gradient background
    • If your prompt is really complex, the model might struggle to do the correct number of sequence stages.

    • I don't fully understand my own model yet so I'll update this as I get more experience with it.

    Tip

    When the start and end sequence look the same, try adding the opposite of what you want earlier in the prompt. Here's an example from the first showcase image:

    Positive prompt:

    1girl, flat chest, small breasts, long hair, white hair, red eyes, smile, straight hair, holding drink, green bikini,
    
    beach,
    
    breast expansion, gigantic breasts, grabbing own breasts, hand on own breast, skindentation, bursting breasts

    Negative prompt:

    low contrast, ugly, desaturated, low quality, blurry, black and white, grayscale, greyscale, text, watermark, sepia

    I start saying flat chest and small breasts before specifying that I want breast expansion and gigantic breasts.

    This doesn't always work, but it has been more consistent for me.

    This is my first-ever LoRA, so it might be a little rough around the edges as I don't really know what I'm doing...
    If you're able to make some good generations with it, feel free to share it with me! I'd love to see what people make.

    Description

    Model feels more consistent from my testing and is a bit more confident in what some of the expansion types are. It seems most confident with 2 stage and 3 stage sequences, however 4 stage sequences are possible.
