A LoRA for four-part horizontal transformation sequences, mainly focused around the door/portal theme but can somewhat work without it if paired with other LoRAs. Focused on [M->F] TG but can do some [F->M] and [F->F] TF if you try. Only works with wide aspect ratios, the wider the better.
(Now updated with better trigger words!)
(Let me know in the comments if you enjoyed, or even just need help getting it to work.)
You can download these and use as reference images to get the desired portal color (strength 1):

If it's not working for you, I suggest emphasizing this LoRA's keyword heavily, adding some synonym of (four people), as well as turning up the LoRA's weight as high as you can handle. HiRes and FaceFix help a lot as well.
(Mainly from the transformation door series, with some similar others added in. If you know any similar series/artwork, however, let me know in the comments - using a bunch of images from the same source made it act a lot like a style LoRA, and more variety would definitely help.)
