>>57222692Novelai v4 preview, make sure I set it to one character, write prompts "(character) transforming into (other character)" and set both base character, and outcome character in the character definitons, then in the image definitions, I put stuff like "mid-transformation", "transforming clothes" "breast growth" "asymmetrical breasts" (to give the illusion of a character's bust size changing while changing)
I also found that the "fusion" tag works well, and of course, make sure to give them a surprised/flustered expression to sell the deal, but nai v4 is smart enough that 9 times out of 10 it knows the effect you're trying to go for.
Also, if you take one of my images I've posted in the thread, and stick it into nai, it'll let you copy just the tags (import metadata) when you use it as a base image so you can see the specifics of the tags I use
