V2:

Much more consistent overall and pose variety increased, as well as making the lower body look more bipedal.

Trigger word is now (conjoined taur), as well as color tags for the upper and lower body. So things like (red upper body), (blue lower body).

if a character has multiple colors you can use multiple upper and lower body tags to clarify them. for example when using incineroar as the upper body I use the following tags. (incineroar), (red upper body), (grey upper body).

If the lower characters head shows up instead of fusing to the upper character, try putting the lower body character in brackets like this [[incineroar]].

I recommend putting (multiple tails) in the negatives as it will sometimes try to give the upper body it's own tail.

You can also improve consistency by using the colored upper and lower body tags in the negatives. For example, you want a lucario upper body and an alligator lower body, in the positives put (blue upper body) and (green lower body), and then in the negatives put the opposite tags, so (blue lower body), and (green upper body).

Tends to work best as a portrait and square, but still works with landscape but is less consistent.

V1:

This lora is for fusing two characters together into one taur with the upper body of one and the lower body of the other. This is technically possible without any loras, but this was made to make it easier for others to do.

Best results are by using both character tags along with (taur) and (solo). You made need to add multiple parenthesis around solo to make it work properly! Adding the tags (fusion) and (conjoined) seem to help but were not in the training data.

The lora will usually make the larger of the two characters the lower body.

For best results use characters that are visually distinct from each other. Similar colored characters with same texture (aka fur vs scales) will likely blend together, Like a character with a red body and a character with an orange body can be difficult to separate cleanly.

Has a strong bias towards male NSFW, use the SFW tag at the beginning if SFW results are desired, lowering the strength will also help with this, but may may the fusion less clean, I have seen it work at strengths as low as 0.5 when using very different characters though it's not consistent.

Does affect style somewhat.

If you are having difficulty fusing two characters together it can help to name the colors of the head, legs in the positive prompts and negative prompts and tail to try and force the result you want. Like, if you wanted a charizard and feraligatr taur with the feraligatr part on top, using (blue head, blue arms, orange legs, orange tail) in the positive tags, and (blue legs, blue tail, orange head, orange arms) in the negative tags, should help it put feraligatr on top.
