So this is a sequence where absolutely everything remained the same - prompt, seed, model, lora weights, etc. - EXCEPT for the weight I assigned to the one belly-specific part of the prompt: "enormous inflated spherical belly." Since I was going for the deliberately spherical look, I wanted to use a prompt that would generally keep the thicker limbs out of it. Each pic has the weight of that particular phrase increased by a little bit: 0.5, 0.8, 1, 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, and 1.7. Those weights were the ones that didn't need any additional input to create a more-or-less good image.
However! After about 1.5, you can see that the belly starts taking on a reddish tint and deforming slightly. And once 1.8 hit, the belly deformed completely into concentric circles, and a giant black ball appeared off to the side. I was able to fix this by adding a couple more belly-related terms to try and temper the overwhelming weight of the "inflated" term, and it worked for just 1.8. Once I got to 1.9, the ball and deformities came back. On a whim, I tried heavily weighting one of the other non-inflation terms to try and "counterbalance" the inflation stuff and ended up with something pretty horrific! Very green, very veiny and the ball didn't even disappear.
Obviously I've gotten larger sizes than this before, but it requires a bit more finessing not just with weights but with the prompt as a whole, the model, the CFG, the resolution, etc. I just thought it would be fun to try and get a whole workable sequence without changing anything but the belleh :D
